Question

A one degree-of-freedom model of a motor vehicle travelling in the horizontal direction is shown in Figure 4.47. Find analytically the relative displacement of the vehicle as it travels over a road bump of the form y(s) Y sin(TTs / delta). Write a MATLAB program for finding the relative displacement of the vehicle as it travels over a road bump of the form y (s) Y sin (ns / delta) and compare the numerical solution to the analytical solution. Use the computer program to find numerically the relative displacement when the vehicle travels over the double step shown below. Parameter values: k 400kN/m, m 1200 kg. zeta = 0.5. Y-O.lm. delta" 6 m.

Explanation / Answer

Q:1) A telephone pole of mass 300kg is 30m long. Its c.g lies 10m from the thicker end. What force must be applied at the thinner end to maintain it in the horizontal position when it is supported at its midpoint?
