When processing a wooden block, the plane under the action of a force of 20 N moves by 0.5.

When processing a wooden block, the plane under the action of a force of 20 N moves by 0.5. calculate the work that is being done in this case.

F = 20 N.

S = 0.5 m.

∠α = 0 °.

A -?

The work of force A is determined by the formula: A = F * S * cosα, where ∠α is the angle between the force F and the displacement of the body S, F is the value of the force, S is the displacement of the body.

Since the force F is directed in the same way as the movement of the body S, then ∠α = 0 °, cos0 ° = 1.

A = F * S.

A = 20 N * 0.5 m = 10 J.

Answer: when processing a bar with a plane, work A = 10 J.
