- The system is made up of a bar, supported by a pin at point A and by a smooth collar at point B (the collar slides on the ABG bar). The collar is pinned to bar BDE, and bar BDE is supported by a pin at D and a cable at end E. Determine the force P such that the force in the cable equals to T. With T= 26 lb, a=4 in, b=9 inarrow_forwardThe cable is loaded by a(n) Q = 73.4-lb vertical force at C and a horizontal force P at B. If x = 3 ft, determine P.arrow_forwardThe spring has a stiffness of 830 N/m and is undisturbed and measures 400 mm. Determine the forces on the BC and BD cables when the spring is stretched in the position shown in the figure.arrow_forward
- A hot air balloon is held in place by three cables anchored to the ground at points B, C, and D. If the tension in cable AD is 1140 N, determine the lifting force of the balloon at A. Take 0 = 26°, $ = 53°, h = 10 m, and a = 4.4 m h В D 4.2 m 2.4 m yarrow_forwardThe chain binder is used to secure loads cf logs, lumber, pipe, and the like. If the tension T is 3.4 kN when 0= 20°, determine the force P required on the lever and the corresponding tension T2 for this position. Assume that the surface under A is perfectly smooth.

Under body A which weighs 200 kN U = 0.20 while U = 0.50 under body B which weighs 300 kN. Determine the angle ⌀ at which motion impends. What is then the tension in the cord?arrow_forward
- A 50-m steel surveying tape has a mass of 1.6 kg. If the tape is stretched between two points at the same elevation and pulled until the tension at each end is 60 N, determine the horizontal distance between the ends of the tape. Neglect the elongation of the tape due to the tension.arrow_forwardThe pipe is stuck in the ground so that when it is pulled upward the frictional force along its length varies linearly from zero at B to fmax (force/length) at C. The pipe has a length L, cross-sectional area A, and the material from which it is made has a modulus of elasticity E. Determine the initial force P required to pull the pipe out. Express your answer as an expression in terms of the variables f, L, A and E and any necessary constants.arrow_forwardBodies A and B are joined by a cord parallel to the inclined plane shown in the figure.
