Answer to Question #144192 in Mechanics | Relativity for Jeshel Kylle Jerlyn Jabanes

Question

1. A 3.0 meters long solid shaft makes an angle of 35 degrees with the horizontal. A vertical force of 50 N
is applied 0.60 m from the upper end. What is the magnitude of the torque due to the vertical force
about each end?

2. A Ladder of 6.0 meters in length weighs 150 N rests on horizontal ground and leans at an angle of 65
degrees with the horizontal against a smooth vertical wall. How far up the ladder may a 700 N person
go before the ladder slips? The coefficient of friction between ladder and ground is 0.40.

3. A Flat bar is loaded with boxes as shown in figure at
right. Box M = 50 kg, what must be the magnitude
of mass m so that the bar becomes level? Neglect
the weight of the bar. What torque about each end
of the bar?
