Question

while the pl plank and speed and pusILIONI.] The 12.2-m crane weighs 18 kN and is lifting a IN load. The hoisting cable (tension T) passes over a pulley at the top of the crane and attaches to an Jectric winch in the cab. The pendant cable (tension 1.), which supports the crane, is fixed to the top of the crane. Find the tensions in the two cables and the force F, at the pivot. edge plan righ cloc pla: 40.0° T T2 10.00 0.00 5.00 LA - 12.2 m 18 kN 67 kN 102
