Slope and Deflection

The slope in a deflected beam is described as an angle in radians made by the tangent of the section with the original axis of the beam. The deflection at any point on the axis of the beam is defined as the lateral displacement of the point before and after loading.

Starting at time t = 0, net force F1 is applied to an object that is initially at rest. (a) If the force remains constant with magnitude F1 while the object moves a distance d, the final speed of the object is v1. What is the final speed v2 (in terms of v1) if the net force is F2 = 2F1 and the object moves the same distance d while the force is being applied? (b) If the force F1 remains constant while it is applied for a time T, the final speed of the object is v1. What is the final speed v2 (in terms of v1) if the applied force is F2 = 2F1 and is constant while it is applied for the same time T? In a later chapter we’ll call force times distance work and force times time impulse and associate work and impulse with the change in speed.)
