Moment of resistance, ususally denoted as W is a term in structural engineering. It is found from the moment of inertia I and the distance from the outside of the object concerned to its major axis e. W = I/e
It is used in structural calculations since the stress can be written as stress=moment/W
It really works much better with graphical explanation which i unfortunately can't add
in simple moment of resistance means couple produce when a beam subjected to bending under the action of loads.

For bulbs connected in series the high watt bulb has high resistance?
No, the highest wattage bulb will have the lowest resistance.
How do you determine internal resistance of voltmeter?
By Ohm's law, resistance is voltage divided by current, so you can determine the resistance of a voltmeter by measuring the total current required to drive it to full scale on each range. In typical digital voltmeters, the resistance is fixed at 11 or 20 megohms by a resistor divider. This is not often affected by range, because the op-amp that picks up the divided signal contributes negligible resistance to the divider. In typical analog voltmeters, the resistance is a function of the resistance selected by the range that is placed in series with the meter movement. An example, for a 50 microampere movement is typically 20,000 ohms per volt, so you simply multiply the selected full scale range by 20,000 to get the resistance.
What is resistant species?
Species resistance is a type of resistance that occurs among all members of a species. This is a part of innate immunity.
Difference between shear connection and moment connections?
As the name goes, shear connection is for resisting shear force only. It stops the two connected members from sliding up and down or back and forth. If two members are connected by a single bolt / pin, they can not move up and down but can move in circle ie rotate, ie the connection has no resistance to turning ie moment. If at this place we put two or more pins or nails, the members will neithe move nor rotate.more pins, bolts , welds more the capacity to resist this turning or angular movement. This is a moment connection. In the actual design of a shear connection the area of pin or bolt (in single or double shear) should be adequate to resists the force which is trying to take it apart. In design of moment connection the moment is transformed into a couple ( two forces at a distance) and the connection is designed ( bolts or welds) for this forces.
When 2 resistors are connected in parallel r1r2 are?
Two resistors connected in parallel are 1/2 the sum of their resistance. The resistance of two resistors connected in series is the sum of their resistance. For example: The total resistance of a 100 ohm resistor connected to a 200 ohm resistor in parallel is 100+200 divided by 2 = 150 ohms. The total resistance of a 100 ohm resistor connected to a 200 ohm resistor in series 100+200= 300 ohms.
What is the moment arm of resistance?
The moment arm of resistance refers to the perpendicular distance from the line of action of a resisting force to the axis of rotation. It helps determine the torque generated by the resistance force on a lever or rotating object. A longer moment arm increases the torque generated by the resistance force.
Maximum moment of resistance of beam?
Rm= 8Mp/L
Definition of moment of resistance of beams?
thats means load In some countries (Greece for sure) by "moment of resistance" we mean Section Modulus, which is Z=I/y, where I: moment of inertia, y: distance from the neutral axis to the most extreme fibre
How do you calculate ultimate moment of resistance?
we can find theultimate moment of resistance by in case of hand lever by followinglength of boss.thickness of boss.tensile stress.(distance from outside of the object concerned to the major axis)
What is the difference between mass moment of inertia and area moment of inertia?
Mass moment of inertia measures an object's resistance to rotational motion due to its mass distribution, while area moment of inertia measures an object's resistance to bending due to its shape and cross-sectional area. Mass moment of inertia depends on both the mass and its distribution, while area moment of inertia depends on the shape and how the material is distributed in the cross-section.
What is moment resistance?
Moment of resistance, ususally denoted as W is a term in structural engineering. It is found from the moment of inertia I and the distance from the outside of the object concerned to its major axis e. W = I/e It is used in structural calculations since the stress can be written as stress=moment/W It really works much better with graphical explanation which i unfortunately can't add in simple moment of resistance means couple produce when a beam subjected to bending under the action of loads.
Can moment of inertia be negative?
No, moment of inertia cannot be negative as it is a physical quantity that represents an object's resistance to changes in its rotation. Negative values for moment of inertia do not have physical meaning.
Define centroid and moment of inertia?
The centroid is the geometric centre of an object. Moment of inertia is a objects resistance to rotation and has the units kg.m^2
What is difference between polar moment of inertia and moment of inertia?
The polar moment of inertia measures an object's resistance to torsional deformation when subjected to a moment of force perpendicular to its axis, while the moment of inertia measures an object's resistance to angular acceleration when subjected to a twisting force. The polar moment of inertia accounts for distribution of mass around an axis, while the moment of inertia considers mass distribution relative to a specific axis.
Mass moment of inertia of a flywheel?
define moment of inertia§ I is the moment of inertia of the mass about the center of rotation. The moment of inertia is the measure of resistance to torque applied on a spinning object (i.e. the higher the moment of inertia, the slower it will spin after being applied a given force).
Must an object be rotating to have a nonzero moment of inertia?
No, an object can have a nonzero moment of inertia even if it is not rotating. Moment of inertia is a measure of an object's resistance to changes in its rotation, so it depends on the object's mass distribution relative to its rotation axis, regardless of whether the object is actually rotating.
What is the rotational analog of mass in linear motion?
The rotational analog of mass in linear motion is moment of inertia. It represents an object's resistance to changes in its rotational motion, similar to how mass represents an object's resistance to changes in its linear motion.
