You place a point force at the tip of the beam in the +Y-direction and displace the cantilever tip by 2 microns. At time t=0, you remove the force from the beam. a. What is the displacement at the beam tip as a function of time? Make sure to solve for all of the constants and write a final equation allowing one to plug in a time and get out the tip displacement. b. What is the displacement at the following times, t=0, t=», t=1.868 microseconds, t=3.736 microseconds, t=5.6046 microseconds?

Develop a finite element model to solve the displacement at the point where the 10000 N is applied (50 cm from the right end). E=20(10°) N/cm² A=8 cm? A=4 cm? 10000 N 3 -75 cm- -50 cm-

Problem 8.61 Part A The two blocks used in a measuring device have negligible weight. The spring is compressed 4 in. when in the position shown. The end of the screw is smooth and the coefficient of static friction at all other points of contact is μ= 0.29. (Figure 1) Determine the smallest axial force P which the adjustment screw must exert on B in order to start the movement of B downward.
