1: Bending moment in a beam was determined to be M(x) = 2000 (x – 2) (N∙m), where x varies from 0 to 2.0 m. Write the angle of rotation (??) as a functions of x, if EI = 2∙106 N∙m2, and ?(0) = 0

2. For the beam in above Problem, calculate the strain energy for x from 0 to 2.0 m.

Homework Answers

Answer #1

1) We have

M= 2000(x -2) = 2000x - 4000

Integrate both sides

Also

=> C = 0

Therefore

2) Strain energy is given by

= 5.33 N-m

A simply supported composite beam (L = 4.5 m) is subjected to a positive bending moment (680 N- m) at both ends. The beam is made of two materials in a square cross-section. Material 1 is 50x50 mm and is surrounded by a 25 mm shell of material 2. Solve for the maximum stress in each material. E1 = 100 GPa, E2 = 200 GPa.

a submarine is 3.00 x 10^2 m horizontally from shore and 1.00 x 10^2 m beneath the surface of the water (n=1.33). A laser beam is sent from the submarine so that the beam strikes the surface of the water 2.10 x 10^2 m from the shore. A building stands on the shore and the laser beam hits a target at the top of the building. The goal is to find the height of the target above sea level. (a)...
