Pushing a Lawnmower Solution(Mastering Physics Chapter 04: Force and Motion)
Consider a lawnmower of weight w which can slide across a horizontal surface with a coefficient of friction μ. In this problem the lawnmower is pushed using a massless handle, which makes an angle theta with the horizontal. Assume that Fh, the force exerted by the handle, is parallel to the handle. Take the positive x direction to be to the right and the postive y direction to be upward. Part A Find the magnitude, Fh, of the force required...

What is the magnitude F_ad of the downward force on section a?
To understand the concept of tension and the relationship between tension and force.This problem introduces the concept of tension. The example is a rope, oriented vertically, that is being pulled from both ends. (Figure 1) LetFu and Fd (with u for up and d for down) represent the magnitude of the forces acting on the top and bottom of the rope, respectively. Assume that the rope is massless, so that its weight is negligible compared with the tension. (This is...
