    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.
