A cylindrical assembly consisting of a brass core and an aluminum collar is compressed by a load P (see figure). Aluminum collar Brass core 270 mm 27 mm *43 mm The length of the aluminum collar and brass core is 270 mm, the diameter of the core is 27 mm, and the outside diameter of the collar is 43 mm. Also, the moduli elasticity of the aluminum and brass are 72 GPa and 100 GPa, respectively. (a) If the length of the assembly decreases by 0.1% when the load P is applied, what is the magnitude of the load (in kN)? KN (b) What is the maximum permissible load Pmax if the allowable stresses in the aluminum and brass are 80 MPa and 120 MPa, respectively? (Enter the magnitude in kN.) KN
