A composite spring consists of two close-coil helical springs connected in series. Each spring has 14 coils at a mean diameter of 20 mm. The stiffness of the composite spring is 800 N/m. If the wire diameter of one spring is 2.5 mm, find the wire diameter of the other. What will be the maximum load which can be carried by the composite spring and the Take G=78 GPa. corresponding deflection for maximum shear stress of 150 MPa?
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
