Question

What should be angle between force and displacement to get the minimum work​

Answer 1

90°

Step-by-step explanation:

This angle is the measured between the force applied and the displacement where the force vector and the displacement vector are on opposite direction.

The formula for work in this case is ;

W=F*d* cos ∅ where ;

F= force, d= distance and ∅ is the work angle

For minimum work ∅ = 90°

For maximum work ∅ = 0°
