Question

isfy the linear equation Fkx+F where k is the spring constant and F is the preload induced during manufactur problem P13. igure P13 Close-wound tension spring for (a) Using the given data in Fig P12 find the equation of the line for the spring force F as a function of the displacement x, and determine the values of the spring constant k 1-4. In a bolted connection shown in Fig. P14, the force in the bolt F is given in terms of the external load P as F (a) Given the data in Fig. P14, deter- mine the joint constant C and the (b) Sketch the graph of F as a function of x. Use appropriate axis scales and clearly label the preload Fi the spring constant k, and both given data points on your graph. Figure P12 Close-wound tension spring for problem P1-2 100 1-3. The spring force F and displacement x for a close-wound tension spring are measured as shown in Fig P13.

The velocity v(t) of a ball thrown up- ward satisfies the equation v(r)v+ at, where vo is the initial velocity of the ball in m's and a is the acceleration in of the load Pand label C and F on 1-5. Repeat problem P1-4 for the data given in Fig. P1.5 a) Given the data in Fig. P1.7, find the equation of the line represent ing the velocity v(r) of the ball, and determine both the initial velocity vo and the acceleration a. b) Sketch the graph of the line v(r), and clearly indicate both the initial ve- locity and the acceleration on your graph. Also determine the time at which the velocity is zero. F, (b P((b) 300 660 1000 3.02 Figure P15 Bolted connection for problem P15.
