Slope and Deflection

The slope in a deflected beam is described as an angle in radians made by the tangent of the section with the original axis of the beam. The deflection at any point on the axis of the beam is defined as the lateral displacement of the point before and after loading.

Problem 10-23
Clamping fixture.
A holding fixture for a workpiece 37.5 mm thick at the clamp locations is being designed. The
detail of one of the clamps is shown in the figure. A spring is required to drive the clamp
upward when removing the workpiece with a starting force of 45 N. The clamp screw has an
M10 X 1.25 thread. Allow a diametral clearance of 1.25 mm between it and the uncompressed
spring. It is further specified that the free length of the spring should be Lo ≤ 48 mm, the solid
height L, 31.5 mm, and the safety factor when closed solid should be n, 1.2. Starting with
d = 2 mm, design a suitable helical coil compression spring for this fixture. For A227 HD
steel, wire diameters are available in 0.2-mm increments between 0.2 to 3.2 mm.

A helical compression spring is needed to fit over a 0.5 in. diameter rod. To allow for some clearance, the inside diameter of the spring is to be 0.6 in. To ensure a reasonable spring size, assume a spring index of 10. The spring is to be used in a machine where it will be repeatedly compressed from a free length of 5 in. to its solid length of 2 in. and then released. The spring should have squared and ground ends and is to be made from a cold-drawn A227 wire. (a) Determine a suitable wire diameter. (b) Determine a suitable total number of coils. (c) Determine the spring rate. (d) Where is the maximum stress in the wire of the spring? (e) Determine the static factor of safety when compressed to its solid length. (f) If the spring is to be designed for infinite life, what will be the mean stress and alternating stress on the spring. (g) Calculate the weight of the spring.
