Carrying Drywall
Two builders carry a sheet of drywall up a ramp.

Assume that W = 2.00 m, L = 3.20 m, θ = 25.0°, and that the lead builder carries a (vertical) weight of 155.0 N (34.8 lb). What is the (vertical) weight carried by the builder at the rear?
(in N)


The builder at the rear gets tired and suggest that the drywall should be held by its narrow side.

What is the weight (in N) he must now carry?
