Question

How can the work done be measured when force is applied at an angke tothe direction of displacement?

Answer 1

Answer:Work measured when force applied is at an angle to the displacement  given by the formula

Work(W)=F.s  or F*s*cos(A)

where A is the angle between displacement and direction of force.

Explanation:

Work done is basically a product (multiplication) of force and displacement in the direction of force.

In other words, mathematically it is expressed as

W=F.s     (dot product of F (force)  ans s (displacement))

W=F*s*cos (A)

Where A is the angle between displacement direction and direction of applied force .

Suppose both force and displacement due to force are in same direction then work done is positive (W=F*s*cos(0))

If both are in opposite direction work done is negative(W=F*s*cos(180))
