- A manager walks d = 3.4 m along a uniform plank supported by the floor at one end and by a vertical rope at the other, as in the figure. Find the tension in the rope if the plank's mass and length are M = 11 kg and L = 6 m, the manager's mass is m = 56 kg, and the angle = 21°. LL T = d— 0 N m 1 Report your numerical answer below, assuming three significant figures. Remember to include a "-" as necessary. HP Search M LDCETimmy and Billy are using a ramp to load furniture into a truck. While rolling a 220-pound piano up the ramp, they discover that the truck is too full with other furniture for the piano to fit. Billy holds the piano in place on the ramp while Timmy repositions other items to make room for it in the truck. If the angle of inclination of the ramp is 25°, how many pounds of force must Billy exert to hold the piano in position? Billy must exert pounds of force.

- A bag of cement weighing 525 N hangs in equilibrium from three wires as suggested in the figure below. Two of the wires make angles ?1 = 61.0° and ?2 = 42.0° with the horizontal.

The figure shows a top view of this looking down onto the crate (gravity would be acting into the page). Man one and man two apply forces F1 and F2, at angles of θ1 and θ2 respectively, with the goal of moving the crate in the x-direction. A resultant force of Fr = 30.5 lbs in the x-direction is required to accomplish this. All of the forces are in the xy plane. If man one applies a force of F1 = 21 lbs at an angle of θ1 = 16° from the positive x-axis, complete the following steps to determine the magnitude and angle of the force man two must apply. c) Combine these two equations to develop an expression for tan(θ2) in terms of Fr, F1, F2, and θ1. Remember that the crate does not move along the y-direction. d)Solve numerically for the value of θ2 in degrees. e)Using this value for θ2 and other known values, solve numerically for the value of F2 in lbs.In the illustration below, the beam is 12 meters long and weighs 20 N (positioned at its center of mass right in the middle).
