A brass alloy to be used for a spring application must have a modulus of resilience of at least 0.75 MPa (110 psi). What must be its minimum yield strength? ( Ebrass = 97 ? 109 ???)

Define the equation of the elastic curve?

The 2014-T6 aluminum rod AC is reinforced with the firmly bonded A992 steel tube BC. ( Figure 1) The assembly fits snugly between the rigid supports so that there is no gap at C. An axial force of P = 390 kN is applied. The assembly is attached at D.

For the indicated part. What would be the maximum torque that can be applied to the indicated part if the bar is solid, made of steel, with a diameter of 5 cm, L = 2m and the total angle of torsion in the length cannot exceed 2 degrees? Assume G = 80 GPa. (Hint: Twist angle has to be in radians to use in formula)
