Answer 1

For the mechanical engineering problem illustrated below, use the appropriate principles and formulas in order to get the accurate solutions for each. Q1. A circular rod of length 15 inches and diameter 0.5 inches is subjected to the tension of 5600lb if the rod is made up of steel E = 29000ksi G = 11000KSI. Find the new cross sectional area? Q2. The stress state at a point in a structure is as illustrated below. All the stresses are in MPA. Determine the normal stress on the plane to the horizontal. Illustrate the direction of the maximum shear stress by respect to the x-axis and determine the maximum shear stress? Q3. This part is subjected to a positive bending moment M = 40Nm. Determine the centroid, moment of inertia and maximum shear stress for the object? Q4. Sketch a free body diagram for the picture below and find out the maximum bending stress and maximum shear stress?
