Moment of force also known as torque depends on
1.magnitude of force F perpendicular to the displacement vector
2.magnitude of displacement vector
Torque is calculated from the following equation
τ is the torque vector
r is the displacement vector
F is the force vector
× cross product
magnitude of perpendicular distance of line of action of force from the pivot,
magnitude of forces(eg. resultant force), resultant moment

Since a moment is a force times a distance is it true to call a moment a force?
No, a moment is a force x a distance, it is the product of a force and a distance. You get the same moment with a force of say 2 Newtons at 0.5 meter as a force of 1 Newton at 1 meter, so it is obviously not a force alone, but the product of a force and a distance, and its units are Newton.meters in the SI system
What is a force that slows things down in the air?
Whenever any object moves through air (eg an aeroplane) it observes four forces 1 Drag force 2. lift force 3.weight of object 4.thrust created by the propellers or engine of the object. The drag force is directed opposite to the direction of moment of the object and slows the object down.
Which is equal to an impulse of 18 units?
Force = 10, time = 3D.Force = 0.1, time = 300
What causes a g force?
g force is the force exerted on a body in the opposite direction to which said body is accelerating. if you're on a rollercoaster and your going not too fast and you suddenly change direction and accelerate quickly, you get pushed back into your seat. g force gets its name as 1g is the equivilent of the force of gravity on the earths surface. That's why when individuals experience g forces greater than 1 or 2, they experience a heavy, weighty feeling and do indeed for a brief moment weigh heavier.Sudden Change In Direction
What 2 things determine the friction between to objects?
Friction between two objects depends on the static coefficient of friction (if the object is currently not moving) and the normal force from the surface, acting in the direction opposite the direction of gravity.
What are 2 things upon which amount of gravitational force between 2 objects depend?
The 2 masses and the distance between them.
What 2 things does an electric force depend on?
An electric force depends on the magnitude of the charges involved and the distance between the charges. The force increases with the magnitude of the charges and decreases with an increase in the distance between them.
Since a moment is a force times a distance is it true to call a moment a force?
No, a moment is a force x a distance, it is the product of a force and a distance.

What are 2 things that the amount of gravitational force between 2 objects depend on?
The amount of gravitational force between two objects depends on their masses and the distance between them. The force increases with the mass of the objects and decreases as the distance between them increases.
What is moment produced by 2 equal and opposite and collinear forces?
The moment produced by two equal and opposite collinear forces is zero. This is because the forces create a balanced system where the clockwise moment produced by one force is canceled out by the counter-clockwise moment produced by the other force.
How do you calculate the moment capacity of a concrete section?
From ACI 318; 1) Solve for a (whitney compressive stress block) 2) Determine moment from force couple
What 2 thing does force depend on?
Force depends on the mass of an object and the acceleration of the object. The equation for force is given by F = m*a, where F is the force, m is the mass, and a is the acceleration.
Shear force bending moment diagram?
a simple definition " IT'S A COUPLE OF FORCE HAVING EQUAL MAGNITUDE BUT OPPOSITE IN DIRECTION & HAVING VERY LESS DISTANCE BETWEEN THEM"
What 2 factors does pressure depend on?
Pressure depends on the force applied on a surface and the area over which the force is distributed. As the force increases or the area decreases, pressure will increase.
What 2 things does the size of the force depend on?
The size of a force depends on two main factors: Mass and Acceleration This relationship can be summarized by the equation: **F = ma** (_where 'F' = Force; 'm' = mass; and 'a' = acceleration)_ *Mass = The amount of matter in an object. **Acceleration = The rate at which an object's velocity changes.
What is the force that holds 2 or more things together?
Lots of forces do that.
What 2 things effect the size of the gravity force between 2 objects?
Mass and volume.
