When calculating moment of force what two changes can be made to increase the size of the moments?
1. increase the force2. increase the distance from the force to the point of moment
Is it possible to calculate the torque acting on a rigid body without specifying the axis?
Not at all possible. Torque defined as the moment of the force about a point or an axis of rotation. Torque tau vector = radius vector x Force vector. Radius is to be measured only from a given point or given axis. Hence axis in very important
What does at any given moment mean?
Right now at any point in timel.
Where is the antinode of a standing wave?
Its the point of maximun displacement at any given moment
What is the unit of moment of force?
It is a vector quantity because it got direction such as clockwise and anticlockwise.now every time a physical quantity having magnitude and direction doesn't have to be a vector. for example current electricity, it has both magnitude and direction but its a scalar quantity.another criteria is that a vector can only be calculated (add,substract) by using vector rules. moment of force can only be calculated using vector methods not algebra methods.so its a vector
What is moment of mass?
Moment=>This is the turning effect of a force about a point

Define moment and moment of a force?
A moment, also known as torque, is a measure of the tendency of a force to cause an object to rotate around an axis or point. It is calculated by multiplying the magnitude of the force by the perpendicular distance from the line of action of the force to the axis of rotation. The moment of a force is the product of the force and the perpendicular distance from the point of rotation to the line of action of the force. It is a vector quantity that describes how much a force tends to make an object rotate. Moments are important in physics and engineering for understanding the effects of forces on objects and structures.
What is the use of shear force and bending moment diagrams?
To determine the internal shear forces and moments at any given point on a rigid body.
What can change when moment changes?
moment depends upon the force and the perpendicular distance between the force and the point where we are finding the moment. so when moment changes either the force will change or the perpendicular distance will change.
What will be the shear force when bending moment is constant?
On SFD's and BMD's: The shear force will be 0, the shear force is the derivative of the bending moment at a point on shear force and bending moment diagrams. Otherwise: It depends on the loading.

What is the value of Shear Force at Point of Contraflexure?
0, bending moment is at maximum
How do you do moment calculations?
force x perpendicular distance from a specific, defined point
Why is the moment of a couple a free vector?
A couple is a mechanical term defined as a system of forces that produces a resultant moment but not a resultant force. The moment caused by a couple is different than the moment caused by a single force. The moment of a force is dependent upon a reference point (i.e. if this reference point changes the moment also changes), therefore it is a fixed (or bound) vector. However, the moment (or torque) of a couple is independent of a reference point. In other words any reference point will give the same torque. This fact is proven in Varignon's Second Moment Thereom. Since the moment (or torque) of a couple is independent of a reference point, it may be represented as a free vector. This means that the vector may be freely moved in space.
What does at any given moment mean?
Right now at any point in timel.
