Question

Determine the amount of work done when a object is displaced at an angle of 30°with respect to the direction of the applied force

Answer 1

Work done is defined as the product of force and displacement (W = Fs)

If the force (F) is applied at an angle (a) to the displacement, then the product of the component of force in the direction of displacement is to be determined.

Therefore, W = F * s * cos a.

Since a is given as 30˚,

W = F * s * cos30

Therefore Work done, W = Fs √3/2
