Question

the ultimate stress, for a hollow stell column which carries an axial laod of 1.9MN is 480N/mm^2 if the external diameter of the column is 200mm determine the internal diameter. take the factor of safty as 4

Answer 1

Answer:

The Ultimate stress for a hollow steel column which carries an axial load of 1.9 MN is 480 N/mm2 If the extermal diameter of the column is 200 mm, determine the internal diameter. Take the factor of safety as 3 1. 2. An axial pull of 35000 N is acting on a bar consisting of three lengths as shown below. If the Young's modulus is 2.1 x 105 N/mm, determine i) Stresses in each section and i Total extension of the bar Section 2 cm 22m
