Two helical compression springs are to be used together with one nested inside the other on a common center-line. The outer spring has an inside diameter of 1:5 in, a wire diameter of 0:125 in, and 10 active coils. The inner spring has an outside diameter of 1:25 in, a wire diameter of 0:092 in and 13 active coils. Both springs have the same free length and a modulus of 11:75 Mpsi. (a) Find the spring constant for each spring. (b) Find the force necessary to compress the assembly by 1 in. (c) At a de ection of 1 in, which spring is more highly stressed

Learning goal: to understand newton's 1st law. newton's principia states this first law of motion: an object subject to no net force maintains its state of motion, either at rest or at constant speed in a right line. this law may be restated as follows: if the sum of all forces acting on an object is zero, then the acceleration of that object is zero. mathematically this is just a special case of the 2nd law of motion, f⃗ =ma⃗ , when f⃗ =0. when studying newtonian mechanics, it is best to remember the 1st law in two ways: if the net force (i. e., sum of all forces) acting on an object is zero, the object will keep moving with constant velocity (which may be zero). if an object is moving with constant velocity, that is, with zero acceleration, then the net force acting on that object must be zero. complete the following sentences to see if you can apply these ideas. part a if a car is moving to the left with constant velocity, one can conclude that
