Question:

Figure P8.57 shows a lightweight plank supported at its right end by a 7.0 -mm-diameter rope with a tensile strength of \(6.0 \times 10^{7} \mathrm{~N} / \mathrm{m}^{2}\).

a. What is the maximum force that the rope can support?

b. What is the greatest distance, measured from the pivot, that the center of gravity of an \(800 \mathrm{~kg}\) piece of heavy machinery can be placed without snapping the rope?image text in transcribed
