A uniform 40.0-kg scaffold of length 60 m is supported by tow light cables below. An 80.0 kg painter stands 1.0 m from the left end of the scaffold, and his painting equipment is 1.5 m from the right end. If the tension in the cable is twice that in the right cable, find the cables and mass of the equipment.

A 20.0-kg horizontal plank 4.00 in long rests on two supports, one at the left end and a second 1.00 m from the right end. What is the magnitude of the force exerted on the plank by the support near the right end? (a) 32.0 N (b) 45.2 N (c) 112 N (d) 131 N (e) 98.2 N

A uniform ladder of length L and mass m1 rests against a frictionless wall. The ladder makes an angle with the horizontal. (a) Find the horizontal and vertical forces the ground exerts on the base of the ladder when a firefighter of mass m2 has climbed a distance x along the ladder from the bottom. (b) If the ladder is just on the verge of slipping when the firefighter is a distance d along the ladder from the bottom, what is the coefficient of static friction between ladder and ground?

Two children of mass 19 kg and 27 kg sit balanced on a seesaw with the pivot point located at the center of the seesaw. a) If the children are separated by a distance of 3.00 m, at what distance from the pivot point is the small child sitting in order to maintain the balance?

Where must a 500 N weight be hung on a uniform 150 N pole with a length of 5 m so that a girl at one end supports ¼ as much as a man at the other end?

Take a piece of modeling clay and put it on a table, then mash a cylinder down into it so that a ruler can balance on the round side of the cylinder while everything remains still. Put a penny 8 cm away from the pivot. Where would you need to put two pennies to balance? Three pennies?

A 3m long weightless beam is supported at each end by cables. A painter weighing 900N stands 1m from the left cable. Calculate the tension in each cable. Please provide complete solution with figures

A 60-kg uniform board 2.4 m long is supported by a pivot 80 cm from the left end and by a scale at the right end (see figure below). (a) How far from the left end should a 40-kg child sit for the scale to read zero? (b) How far from the left end should a 40-kg child sit for the scale to read 100 N?

A uniform pole 20 feet long and weighing 80 lbs is supported by a boy 2 feet from end A and a man 5 feet from end B. At what point should a load of 100 lbs be placed so that the man will i support twice as much as the boy? Include fb, formula and given
