Work - Example Problem 7.1-7

 

A bushing slides on a shaft that forms a 20o angle with respect to the x-axis. A constant force F = 5i + 4j N acts on the bushing. Determine the work the force performs on the bushing if it moves a total distance of 2 m along the shaft.

 

 

Given:
  • θ = 20o
  • F = 5i + 4j N
  • d = 2m
