Solution does not answer question. What is the tension of both wires?
by Bartleby Expert- A bridge crossing a ravine has mass Mb and length L. The bridge is supported by pilings at points A and B at the right and left ends. A truck of mass mt stops at the point L/3 from point B. Find expressions for Fa and Fb, the forces supporting the bridge at each end.Q4.2. A springboard-type diving board is built from high grade aluminum. This particular board has a mass of 65 kg and is 3.85 m long. 33.8 cm wide, and 5 cm thick. (Aside: Most springboards start thick on one end, then get thinner as it moves to the other end. For this problem, assume the springboard has a constant thickness) One end of the springboard is attached to a hinge. The hinge lets the springboard move up and down, but keeps it from sliding out of place. 1.1 m away from the hinge, the springboard rests on (but is not attached to) a fulcrum. A diver with a mass of 65 kg stands on the far end of the springboard (opposite from the hinge), ready to begin their dive. Hinge Fulcrum Note: the measurements for this problem were taken from the springboards used in the 2016 Summer Olympics, 3 m Springboard event.The diagram shows a sign that wighs 50 N hanging from a uniform horizontal pole. The pole weighs 30 Newton's and it is 1.6 m long. Determine the tension in the supporting cable C and the magnitude and direction of the two component forces at the pivot, P, exert on the pole.
- I need Part A and Part BWhen a person stands on tiptoe (a strenuous position), the position of the foot is as shown in Figure a. The total is supported by the force n exerted by the floor on the toes of one foot. A mechanical gravitational force on the body, F model of the situation is shown in Figure b, where T is the force exerted by the Achilles tendon on the foot and R is the force exerted by the tibia on the foot. Find the values of T, R, and 0 when F, = n = 770 N. (For 0, enter the smaller of the g' two possible values between 0° and 90°.) -Achilles tendon Tibia 15.0° 18.0 cm 25.0 cm a T = R = N = Submit AnswerThe truss structure in a Figure Q4a is supported at A and B and has three forces acting vertically at nodes D, E and C, where F₁ = 25 KN, F2 = 75 kN and F3 = 35 kN.

- pls write clearlyA 30 kg mass is supported at the end of a horizontal beam of negligible mass that is hinged to a pole as shown. A cable at an angle of 42 with the beam helps support the weight. Find the tension in each cable, T1 and T2.A fence post of mass m = 8 kg supports a fence with three lengths of barbed wire. The bottom wire is a distance d = 0.35 m from the ground and each wire is a distance 0.35 m above the previous one. Each of these three wires has the tension on it. For this problem, assume that the force exerted by these wires is purely horizontal. An additional guy wire is used to keep the pole upright with a tension of Fa = 490 N. The guy wire attaches to the post at a point h = 0.86 m above the ground and makes an angle of θ = 45 with respect to the horizontal. Write an expression for the tension in any one of the three fence wires. What is the normal force that the ground exerts upward on the post?
