Question

4.2 A 2800-kg forkdift truck is used to lift a 1500-kg crate. Determine the reaction at each of the two (a) front wheels A, (

Answer 1

Answer #1

A)

Taking moment about point B,

(Ra x 0.9) - (2800 x 9.8 x 0.3) - (1500 x 9.8 x 1.3) = 0

Ra = 30.41 kN

Reaction force at wheel A, R_A = 15.21 kN

B)

Taking moment about point A,

(Rb x 0.9) - (2800 x 9.8 x 0.6) - (1500 x 9.8 x 0.4) = 0

Rb = 11.77 kN

Reaction force at wheel B, R_B = 5.89 kN
