QUESTION 3 Describe physical meaning of mode shape of vibration.

5. Given: Structure shown below Find: (1) Orientation of the principal axes having an origin at C and (2) principal moments of inertia about these axes 100 mm- 20 mm 20 mm 150 mm 150 mm, -100 mm-20 mm

(a) What is the dimension of an area moment of inertia?(b) If the thickness of a piezoelectric cantilever beam increases, does the natural frequencyincrease or decrease?(c) Both the thickness and width of a piezoelectric cantilever beam can change the natural frequency. Which parameter (thickness or width) will lead to the natural frequency change more significantly? Briefly explain your answer.

Problem # 2 For the figure shown find the moment of inertia about the centriodal axis: 200 mm 3" 20 mm 16" 8" 260 mm 20 mm 20 mm 6"

I'm still confused on your solution could you go over each step again but in more detail. Like for the reactions are you finding the reactions at A and G. You wrote reaction at A and B so I'm a little confused. If so how did you know to take the reaction at those points and how did come about that equation for the reactions. How does x vary from 0 to 24 and 24 to 36.

Urgent , looking for right answer.

Which of the following is NOT true of Elastic Modulus. It can be looked up using the Material Properties table in the textbook or another similar source like engineeringtoolbox.com It is a material property and should be approximately the same value for samples of the same material It describes the behavior of a material after yielding (permanent deformation). It links stress and strain, allowing us to predict things like a change in material shape due to a specific load. 2000
