Machine Design Textbook problem

AI Thread Summary
Assistance is requested for solving a machine design textbook problem, specifically focusing on calculating weight based on a pointer's deflection and sensitivity. The problem involves a 10-degree deflection with a sensitivity of 0.5 lb/degree, leading to a weight calculation. Additionally, the spring compression force can be determined using trigonometric principles. The discussion emphasizes the importance of attempting the problems independently before seeking help. Clear guidance on summing forces and calculating distance X is provided.

Problem 3: Here is start however you should attempt to solve these problems before you ask for assistance. Assume the pointer deflects 10 degrees. For a sensitivity of .5 Lb/degree what would the weight be? Knowing the deflection in degrees you can also calculate the spring compression force using trig. Sum the forces about A to find the distance X.
