In this section, attention is directed to closely coiled standard helical tension and compression springs. They provide a push or pull force and are capable of large deflection. A helical compression spring is fabricated from ASTM A229 oil-tempered wire (Figure 1) and has the mean coil diameter D = 10 mm, wire diameter d = 0.9 mm, total number of active coils Na = 14.5, and the modulus of rigidity G = 79 GPa. Find: a. The torsional yield strength of the wire. b. The static load corresponding to the yield strength and spring constant. c. The solid and free heights and the pitch of the body coil of the spring. d. Whether buckling will be possible, if the ends are squared-ground.

Statics of Rigid Bodies Note: If you have already answered the problems in this post, kindly ignore it. If not, then answer it. Thank you, Tutor! Content Covered: - Method of Joints Direction: Create two problems based on the topic "Method of Joints" and then solve them with a complete solution. In return, I will give you a good rating. Thank you so much! Note: Please bear in mind to create two problems based on the topic "Method of Joints." Be careful with the calculations in the problem. Kindly double check the solution and answer if there is a deficiency. And also, box the final answer. Thank you so much!
You are given a metal rod, cut to a length of 12 in plus/minus .25in. Then you need to cut off 2 in with an accuracy of plus/minus .25 tolerance. You end up with a 10 in rod but what is the tolerance? (hint: rely on the basic principle of tolerance
Please guide me through the procedure of thoroughly testing individual components.
please provide the following: speed rate, deep of cut and measurements of a meat mallet.
Please help. Do not just guess. Prove your answer. I will give a good feedback.
