Question:
The worker uses the hand truck to move material down the ramp. If the truck and its contents are held in the position shown and have weight W with center of gravity at G, determine the resultant normal force of both wheels on the ground A and the magnitude of the force required at the grip B.
Given:
W = 100 lb e = 1.5 ft
a = 1 ft f = 0.5 ft
b = 1.5 ft θ = 60 deg
c = 2 ft ϕ = 30 deg
d = 1.75 ft
FB (90°-0) (90°-8) e+f (0-0) NA

Take 2 forks and place them on one another in such a way that we can place the coin in between the prongs. Now try to place the coin with forks on the edge of the glass. It will take you some time to adjust the coin on the edge. This requires a little practice to adjust the coin on the edge of the glass. With a little effort, we will see the coin sitting on the edge calmly. If you look closely you will see it wobbling a little bit. The mass is in the handles of the forks so as a low center of mass it stables as it looks.
