Answer

given,

mass of crate attached by cable A  = 160 Kg

mass of crate attached by cable B  = 73 Kg

acceleration of helicopter = 1.4 m/s²

tension in the cable when the move up

F = m (a + g)

tension in cable B

F = 73 x (1.4 + 9.8)

F = 73 x 11.2

F = 817.6 N

tension in cable A

F = (160 + 73 ) x (1.4 + 9.8)

F = 233 x 11.2

F = 2609.6 N
