Solved by Expert Dave Kratz

Step 1

The mean diameter of the spring can be calculated using the formula: Mean diameter = helix diameter + wire diameter Mean diameter = 0.80 in + 0.08 in Mean diameter = 0.88 in Show more…

Questions 18 through 20 refer to a helical compression spring with plain ends. The following information is provided: helix diameter, wire diameter, number of coils, free length, and shear modulus. The values are as follows: helix diameter = 0.80 in, wire diameter = 0.08 in, number of coils = 15, free length = 2.0 in, and shear modulus = 11.5 lbf/in^2. The spring constant is 1.66 lbf/in. 19. The force required to compress the spring solid is 1655 lbf.
