Question

How is moment calculated in the following condition? write formula only.i. when force is parallel to the distance between the fulcrum and the line of action of force.ii. when force is forming an angle smaller than 90 degree with the distance between the fulcrum and the line of action of the force.​

Answer 1

Answer:

A moment or torque of a force is a measure of that force's tendency to cause a rotational acceleration in the same way that a force causes a linear acceleration.

In its simplest form, where a force of magnitude F is acting a perpendicular distance d from the point of rotation, the torque about that point is given by:

τ=Fd

More generally, the equation for calculating the magnitude of a torque τ_ due to a force F_ is:

τ=dFsinθ

or in vector notation:

τ_ = d_ × F_

where d is the distance or d_ is the displacement from where the force is acting on the object to the point of rotation and θ is the angle between d and the line of action of the force.
