Awrecking
ball (weight = 4800 N) is supported by a boom, which maybe assumed
to be uniform and has a weight of 3600 N. As the drawingshows, a
support cable runs from the top of the boom to thetractor. The
angle between the support cable and the horizontal is32 degrees,
and the angle between the boom and the horizontal is 48degrees.
Find (a) the tension in the support cable and (b) themagnitude of
the force exerted on the lower end of the boom by thehinge at point
P.

Answer:

The tension force in the cable is 4800N and the magnitude of the force exerted on the lower end of the hinge at point P is 9335N. The forces were resolved into components and were used for the fore summation. This makes it easier to apply newtons first law of motion

Explanation:

The step by step solution to this problem can be found in the attachment below. A free body diagram is drawn for the wrecking ball which makes it easier to obtain the the tension in the cable.

Next a summation of forces acting on the boom (the weight, the tension in the cable and the reaction at the base) and from that all other unknowns can be calculated. Best regard my pleasure it is to provide answer the question. I hope you do find it useful. Thank you
