Two helical compression springs are to be used together with one nested inside the other on a common center-line. The outer spring has an inside diameter of 1:5 in, a wire diameter of 0:125 in, and 10 active coils. The inner spring has an outside diameter of 1:25 in, a wire diameter of 0:092 in and 13 active coils. Both springs have the same free length and a modulus of 11:75 Mpsi. (a) Find the spring constant for each spring. (b) Find the force necessary to compress the assembly by 1 in. (c) At a de ection of 1 in, which spring is more highly stressed

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?
