How Much Force Is Needed to Push a Piano Up a Ramp?

Click For Summary
SUMMARY

The discussion focuses on calculating the force required to push a 160 kg piano up a ramp inclined at 36.9 degrees, neglecting friction. The solution involves applying the equation for the summation of forces along the incline, leading to the conclusion that the force exerted by the man is 941 N. This calculation utilizes the weight of the piano and the sine of the angle of inclination to determine the necessary force.

Homework Statement


A man pushing a piano with a mass 160kg at constant velocity up a ramp that is inclined at 36.9 degrees above the horizontal. Neglect friction. If the force applied by the man is parallel to the incline, calculate the magnitude of this force.

Homework Equations





The Attempt at a Solution


summation of Fx = wsin(alpha) - Fman = 0
Fman = (160kg)(9.8)(sin(36.9))
= 941N
