SELF-CHECK EXERCISE PROBLEM 04.
A 30 KN of force at one end just supports a weight of 30,000 KN load at the
other end. If the rope is run three times around a circular post, what is the
coefficient of friction between the rope and the post?

Directions: Assume, unless otherwise specified, that all numbers have at least 3 significant figures. F (N) Students collect data, see graph, for the force involved in stretching a rubber band. The data is well fit by the equation F = 33.65 x0.4971, 12 10 where F is in newtons and x is in meters. One end of the rubber band is attached to a stationary vertical rod and the other end to a 0.3 kg mass. The mass rests on a frictionless horizontal surface. The mass is pulled back such that the rubber band is stretched by 0.8 m from its unstretched length and then released from rest. 4. x (m) 0,1 0.02 0.04 0.06 0.08 A. What is the speed of the mass after it has traveled 0.4 m? B. What is the maximum speed of the object?
3m 5m A B 4m Figure 2 4. A thin horizontal beam of negligible mass is hinged at one end A and supported at the other end B by a string, shown in Figure 2. The string can withstand a maximum tension of 30 N. A possum of mass m = 3 kg walks out along the beam. How far along the beam can the possum go before the string breaks?
Question 2: #52 An 80 kg construction worker sits down 2.0 m from the end of a 1450 kg steel beam to eat his lunch, as shown in Figure below. The cable supporting the beam is rated at 15,000 N. Should the worker be worried?
A 2.00 m long horizontal uniform beam of mass 20.0 kg is supported by a wire as shown in the figure. The wire makes an angle of 20.0 degrees with the beam. Attached to the beam 1.40 m from the wall is a ball with a mass of 40 kg. What is the tension in the string? a)1,000 Nb) 1,090 N c) 2,100 N d) 2,250 N e) 2,680 N

What's the force on each rope if the person is standing 1.75 m from one end?
A homeowner is trying to move a stubborn rock from his yard. By using a a metal rod as a lever arm and a fulcrum (or pivot point) the homeowner will have a better chance of moving the rock. The homeowner places the fulcrum a distance ?=0.288 mfrom the rock, which has a mass of 465 kg, and fits one end of the rod under the rock's center of weight. If the homeowner can apply a maximum force of 671 N at the other end of the rod, what is the minimum total length ? of the rod required to move the rock? Assume that the rod is massless and nearly horizontal so that the weight of the rock and homeowner's force are both essentially vertical. The acceleration due to gravity is ?=9.81 m/s2.
A 9 m long board that has a mass of 14. Each end is held up by a vertical rope. A 45 kg box sits 1 m from the left end. Find the tension in the rope on the right. Hint: With forces applied at different places, this is a beam problem pick a pivot point measure all distances from the pivot point Apply Στ = 0 Don't forget torque = force x dist, so you need to multiply the masses by g = 9.8 m/s2 If you need more information, apply ΣF = 0
