A small hoist is mounted on the back of a pickup truck and is used to lift a 12kg crate. Determine (a) the force exerted on the hoist by the hydraulic cylinder BC, (b) the reaction at A.© BrainMass Inc. brainmass.com February 24, 2021, 2:32 pm ad1c9bdddf
First angle ACB = 90 -30 -15 = 45
So AC = 0.4*sin 15 /sin 45 = ...
Trigonometry is used to solve for forces. The force exerted and reactions in static are determined.
