You are holding a fridge of width, b, and length, d, at an angle so that it does not topple over by exerting a force, Fyf, at a height, h, as indicated in the diagram below. For simplicity, assume that fridge is a uniform object so that the weight from the Earth on the fridge acts through its center. You can also assume that ground is so slick that there is negligible friction between the fridge and the ground.

Question
a. Draw an Extended FBD of fridge.
b. Solve for the contact force from the ground on fridge, FGf, in terms of the geometric
parameters shown in the diagram, the mass of the fridge (m), and g.
c. Solve for the contact force from the you on fridge, Fyf, in terms of the geometric
parameters shown in the diagram, the mass of the fridge (m), and g. Your answer can
also have FGf in it if you solved for it in part b in terms of the known quantities as then
FGf becomes a known quantity.
