The term fluid represents a type of substance that can easily change its shape under any external pressure/force and can flow. Fluids can acquire any shape in which it is stored and can resist normal stresses but cannot resist shear stress in rest condit…

Textbook Question

Chapter 5, Problem 5.23P

The period T of vibration of a beam is a function of its length L, area moment of inertia I, modulus of elasticity E, density ρ , and Poisson’s ratio σ . Rewrite this relation in dimensionless form. What further reduction can we make if E and I can occur only in the product form EI? Hint:

Take L, ρ , and E as repeating variables.

The natural frequency ω of vibration of a mass M attachedto a rod, as in Fig. depends only on M and the stiffness EI and length L of the rod. Tests with a2-kg mass attached to a 1040 carbon steel rod of diameter12 mm and length 40 cm reveal a natural frequency of 0.9 Hz.Use these data to predict the natural frequency of a 1-kgmass attached to a 2024 aluminum alloy rod of the samesize.

The partial di§erential equation for the small-amplitude vibrations of a string of length ` is given by A@2y@t2T@2y@x2 = 0 where y(x; t) is the vibration amplitude, is the material density of the string, A is the string cross sectional area, and T is the tension force in the string. Using only the parameters given, make this equation dimensionless. Hint 1: first find a combination of ` and/or and/or A and/or T to make x, y, and t dimensionless.(It is clear that a different combination will be needed to make t dimensionless than that for x and y.) Hint 2: let c = q TA . What are the dimensions of c? (Note that c is known as the ìwave speed.î)

Given: lambda = 10 m, mass of the vehicle, m= 1000kg, k=9000 N/m, speed 60/2pi m/s. Interpret this graph for me. What happens if we go to the right? What happens if we go to the left? If we want to have a great magnitude of vibrations according to the graph should we increase or decrease our speed? explain. What if b is decreasing but we maintain our speed would b decrease or increase the magnitude? Why? If we are driving at the speed that always maximizes the magnitude of the shaking will decreasing b increase or decrease magnitude?
