A young work crew is trying to quickly finish some touch-up painting to complete a job. Rather than setting up a secure workarea, they decide to try a shortcut.Worker A will hold the far end of a 9.47 m work plank that weighs 114 N and is secured with a hinge on the opposite end.Worker B will stand on the plank 4.55 m from worker A. Worker B also brings up his paint can of mass m₁ = 3.48 kg, which heplaces 0.490 m from where he is standing on the plank (between the two workers). Worker A needs to supply 509 N of force tokeep the end of the plank stable.The acceleration due to gravity is g = 9.81 m/s².How much WB does worker B weigh?

Beverage engineering. The pull tab was a major advance in the engineering design of beverage containers. The tab pivots on a central bolt in the can’s top.When you pull upward on one end of the tab, the other end presses downward on a portion of the can’s top that has been scored. If you pull upward with a 10 N force, what force magnitude acts on the scored section? (You will need to examine a can with a pull tab.)
A 11.0-kg monkey climbs a uniform ladder with weight w = 1.40 × 102 N and length L = 2.60 m as shown in the figure below. The ladder rests against the wall and makes an angle of 0 = 60.0° with the ground. The upper and lower ends of the ladder rest on frictionless surfaces. The lower end is connected to the wall by a horizontal rope that is frayed and can support a maximum tension of only 80.0 N. Rope (a) Draw a force diagram for the ladder. Choose File no file selected This answer has not been graded yet. (b) Find the normal force exerted on the bottom of the ladder. (c) Find the tension in the rope when the monkey is two-thirds of the way up the ladder. N (d) Find the maximum distance d (along the ladder) that the monkey can climb up the ladder before the rope breaks. (e) If the horizontal surface were rough and the rope were removed, how would your analysis of the problem change? What other information would you need to answer parts (c) and (d)?

Three children are trying to balance on a seesaw. The seesaw is 4.1 m long and pivots about a rock at its center. Louie and Laura are already sitting on opposite ends. If Martha weighs 33 kg, where should she sit so as to balance the seesaw?
A diving board of length 4.00 m is supported at a point 1.50 m from the end, and a diver weighing 500 N stands at the free end. The horizontal diving board is supported at the point 1.50 meter away from its left end.
