The uniform seesaw shown below is balanced on a fulcrum located d1 = 3.5m from the left end. The bigger boy on the left end has a mass m1 =75 kg. The smaller boy on the right end has a mass of m2 = 55 kg and is a distance d2 = 4.5 m from the fulcrum. The mass of the board is mb.    Draw all forces acting on the seesaw board showing their directions and locations. Where would you draw the weight of the board? Identify and show the direction of rotations caused by the torques provided by all forces about the fulcrum. If the seesaw is in static equilibrium, write down the two conditions of static equilibrium symbolically using the forces and distances in the figure. Solve for the mass of the board. Calculate the force of fulcrum on the board.

A uniform beam of length L = 7.10 m and weight 4.05 × 10² N is carried by two workers, Sam and Joe, as shown in the figure below. Determine the force that each person exerts on the beam. Sam Joe F F Sam II = -1.00 m N N Z Z -2.00 m- L

A 12 000-N shark is supported by a rope attached to a 4.60-m rod that can pivot at the base. (a) Calculate the tension in the cable between the rod and the wall, assuming the cable is holding the system in the position shown in the figure. (Give you answer to three significant digits.) b) Find the horizontal force exerted on the base of the rod magnitude ------- N c) Find the vertical force exerted on the base of the rod. Ignore the weight of the rod. magnitude ------ N

Problem As shown below, a horizontal beam is in equilibrium. The orange circle represents the hinge and the 5 m long cable has a tension of 594 N. 3 m 5 m 4 m 2 162 N CEFFER C Bw #3 Determine the weight of the beam as well as the magnitude & direction of the force that the hinge exerts on the beam. beam weight = hinge force magnitude = hinge force direction = $ 4 21 % 5 o relative to the horizontal.
