Question

Part A Find TA, the tension in string A. The figure (Figure 1) shows a model of a crane that may be mounted on a truck.A rigid uniform horizontal bar of mass mi80.0 kg and length L 6.00 m is supported by two vertical massless strings. String A is attached at a distance d 2.00 m from the left end of the bar and is connected to the top plate. String B is attached to the left end of the bar and is connected to the floor. An object of mass m2 -3000 kg is supported by the crane at a Express your answer in newtons using three significant figures View Available Hint(s) Figure ? 1of1 ? Submit Part B Find TB, the magnitude of the tension in string B Express your answer in newtons using three significant figures View Available Hint(s) in1

Answer 1

m₁ = 80 kg

L = 6 m

d = 2 m

m₂ = 3000 kg

Part A )

the net torque here is zero

T_A d - m₁ g L/2 - m₂ g x = 0

T_A = ( m₁L/2 + m₂ x ) (g/d )

x vlaue missing remaining all values are avilable

plug in the values and finalise T_A

Part B )

T_A - T_B - m₁ g - m₂ g = 0

T_B = T_A - m₁ g - m₂ g

from above T_A, m₁, m₂ and g values

finalise T_B value.
