3. A 14m long steel cable with nominal diameter 19.5mm is used to lift a bridge section weighing 38 kN as shown. How much will it stretch when the load is picked up? If the cable is rated for a max load of 70 kN, what is the factor of safety with respect to fallure of the cable? The effective modulus of elasticity is E = 140 GPa. Take the ultimate load as 406 kN.

After an unfortunate accident at a local warehouse, in which a jib crane collapsed and injured a worker, the owners want to determine the cause. A diagram of the jib crane is shown in the image. The horizontal steel beam had a mass of 93.60 kg per meter of length and the tension in the cable was T = 12.69 kN. The crane was rated for a maximum load of 1000 lbs. Consider that d 5.580 m, S = 0.594 m, X = 1.450 m, and h 1.890 m. What was the load WL on the crane before the collapse? WL N W. What was the magnitude of force at the attachment point P? Fp

For the two-bar truss shown in Fig: 03, determine the displacement in the y direction of node 1 and the axial force in each element. A force of P =1000kN is applied at node 1 in the positive y direction while node 1 settles an amount δ=50mm in the negative x-direction. Let E=210GPa and A=6.00x10-4m2 for each element. The length of the elements are shown in Fig: 03

The uniform 44 kN bar BC is supported by a pin at C and the aluminum wire AB. The cross-sectional area of the wire is 178.5 mm2. Assuming bar BC to be rigid, find the vertical displacement of B due to the weight of the bar. Use E = 71 GPa for aluminum. Anwer must be in mm.

Rope BCA passes through a pulley at point C and supports a crate at point A. Rope segment CD supports the pulley and is attached to an eye anchor embedded in a wall. Rope segment BC creates an angle of ø = 64.0 ° with the floor and rope segment CD creates an angle 0 with the horizontal. If both ropes BCA and CD can support a maximum tensile force Tmaz = 165 lb. what is the maximum weight Wmar of the crate that the system can support? What is the angle e required for equilibrium? Express your answers numerically in pounds and degrees to three significant figures separated by a comma. • View Available Hint(s) nν ΑΣφ vec Wmax.0 = lb, degrees

The aluminum pipe shown in Fig. is used to support a load of 150 kip.Determine the maximum displacement at the top of the pipe if the load is(a) applied gradually, and (b) applied by suddenly releasing it from the topof the pipe when h = 0. Take Eal = 10(103) ksi and assume that thealuminum behaves elastically.

A circular nylon pipe supports a downward load PA= 10 kN. which is uniformly distributed around a cap plate at the lop of the lower pipe. A second load PB=20 kN is applied upward at the top. The inner and outerdiameters of the upper and lower parts of the pipe are d1= 50 mm, dz= 60mm, d3= 55 mm, and d4=65 mm. respectively.The bottom pipe has length 400 mm and the upper pipe has length 300 mm.(a) Calculate the axial normal stress in each pipe segment.(b) Calculate the strain in each pipe segment if the elongation of theupper pipe is 3.29 mm and the elongation of the bottom part is 1.25 mm.

The total load W is to be lifted using the mast hinged at B. The mast is of uniform section and wighs 8kn.  If allowable tensile force in the cable AC is 45kn what is the maximum load W (kn) that can be lifted?

Please assist me in drawing the free body diagram. I'm not sure what happened at C for member ABC.
