Two painters stand on a 10.0m long plank of mass 300 kg. The plank rests on two pillars separated by 6.00m. Danny has a mass of 92.0 kg and stands 3.00m from the left end of the plank and Jerry has a mass of 68.0 kg and stands 1.50m from Danny. Assume that the plank is not nailed to the pillars (the plank only rests on top of pillars).

To balance a 35.5-kg automobile tire and wheel, a mechanicmust place a 50.2-g lead weight 25.0 cm from the center of thewheel. When the wheel is balanced, its center of mass is exactly atthe center of the wheel. How far from the center of the wheel wasits center of mass before the lead weight was added?
A gymnast with mass 46.0 kg stands on the end of a uniform balance beam as shown in the figure. The beam is 5.40 m long and has a mass of 250 kg (excluding the mass of the two supports). Each support is 0.540 m from its end of the beam. In unit-vector notation, what are the forces on the beam due to (a) support 1 and (b) support 2?

A mechanic is screwing a bolt and applies a force ?⃗ ofmagnitude 12.0 N to the end of the wrench. The force makes an angle θ =35.0∘with the horizontal, and the wrench is positioned vertically. The distance fromthe bolt to the end of the wrench is ? = 25.0cm. Find the torque on the bolt exertedby the force ?⃗. (Consider the sign of the torque in your answer, positive if torque iscounterclockwise and negative if torque is clockwise).
