A 35.0 kg uniform beam is attached to a wall with a hinge while its far end is supported by a cable such that the beam is horizontal. If the angle between the beam and the cable is θ = 59.0° what is the tension in the cable?

200.077 N

Explanation:

Mass of beam m= 35.0kg

This is a torque problem

Sum of torques should be zero for equilibrium

Marque along point A is

weight force × half legth of beam - T sin (59°) × Length of the beam=0

35.0 × 9.8 × L/2 = T ×  0.8571673007 × L

==> 343 /2 = T× 0.8571673007

==>  T= 200.077 N

prolly a beacuse the momentuem the car has increases while going down hill

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement
