Liquids and gases do not have Young's moduli because they do not exhibit the same elastic behavior as solids. Young's modulus is a measure of a material's stiffness or rigidity, which is a characteristic only observed in solid materials. In liquids and gases, the particles are free to move past each other, leading to their inability to resist deformation in a purely elastic manner.
Only integer multiples of the elementary charge (1.6 x 10^-19 coulombs) are observed in matter on the atomic scale. Non-integer or half-integer values of charge are not observed in nature.
Type your from the hook's law, stress is directly proportional to the strain under the elastic limits. σ α ε where, σ - tensile stress. ε - strain. now σ =E ε where, E is the proportionality constant or the young's modulus of the material. the extension of the hook's law where the shear stress is directly proportional to the shear strain. ζ α γ ζ - shear stress. γ - shear strain. ζ = Gγ where G is the modulus of rigidity. A pure shear stress at a point can be alternatively presented by the normal stresses at 450 with the directions of the shear stress. σ1 = -σ2 = ζ. using this principle you get G = E/(2(1+ ν)) is the 1 equation. where, ν is the poisson's ratio.this is the basic relation between E,G, ν. the change in volume per unit volume referred to as the dilation. e = εx + εy + εz the shear strains are not taken into account because they do not contribute to any volume change. for an isotropic linearly elastic materials for use with Cartesian coordinates εx = σx/E - νσy/E - νσz/E similar equations are formed for εy ,εz . e = εx + εy + εz = ((1 - 2ν)/E)( σx+ σy+ σz) if σx= σy = σz = -p like a hydrostatic pressure of uniform intensity then -p/e = k = E/3(1 - 2ν) is the 2 equation where k is the bulk modulus. Addin 1 & 2 by bringing only the poisson's ratio to left side and taking all other constants to the right side the equation formed is the 9/E = 3/G + 1/k is the relation between the three modulus. here...
If the mechanical advantage of the pulley system is 4, the operator will only need to apply 1/4 (or 25%) of the force needed to lift the weight on their own. This means the force required by the operator will be one-fourth of the weight being lifted.
The mechanical advantage of 4 means the operator only needs to apply a quarter of the force needed to lift the engine. Therefore, the operator will only need to apply 500 newtons of force to lift the 2000 newton engine.
True
modulus (%) and shift (<<, >>) for examples.
true
Both statements are true.
A conjunction is a mathematical operator that returns an output of true if and only if all of its operands are true.
An operand is the value that is being operated upon by an operator. For instance, the C++ increment operator (++) is a unary operator, which means it has only one operand, the variable that we wish to increment. This in the expression x++, x is the operand. The addition operator (+) is a binary operator and therefore has two operands. Thus in the expression x + y, x and y are the operands.
A variation of the AND NOT Boolean operator is the "NOR" operator, which returns true only if both operands are false.
A ternary operator takes 3 operands. The only one I can think of in C# or C is the"? :" operator: ? : For example:Console.Write(1==2 ? "Huh?" : "Impossible"); //Impossible is printed
in C++ there is no real difference as operators are overloaded by implementing them as functions. However, while we differentiate between function overloads by the function signature (the number and type of parameters), operator overloads are distinguished only by the parameter types. The parameters are interpreted as operands, and the number of operands will depend upon whether the operator is unary, binary or ternary. That is, for any given operator, the number of operands will be the same for each overload you implement. The only exceptions are the unary increment (++) and decrement (--) operators as they each have postfix and prefix variants. In order to differentiate their signatures, an unreferenced or dummy parameter must be passed to the postfix variants.
The symbol in Boolean logic represents the operator "AND," which returns true only if both operands are true. It is often represented by an asterisk (*) or a dot (•).
The conditional operator (? :) is a ternary operator (it takes three operands). The conditional operator works as follows:The first operand is implicitly converted to bool. It is evaluated and all side effects are completed before continuing.If the first operand evaluates to true (1), the second operand is evaluated.If the first operand evaluates to false (0), the third operand is evaluated.The result of the conditional operator is the result of whichever operand is evaluated - the second or the third. Only one of the last two operands is evaluated in a conditional expression.
There is no unary plus in C, but if there were, it would have only one operand, unlike the binary plus which has two: x = a + b; /* binary plus */ x = + b; /* unary plus -- not in C*/ x = a - b; /* unary plus */ x = - b; /* unary minus */
