Question

1. The Ultimate stress for a hollow steel column which carries an axial load of 1.9 MN is 480 N/mm². If the external diameter of the column is 200 mm, determine the internal diameter. Take the factor of safety as 3. 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 2.1x10? N/mm², determine i) Stresses in each section and ii) Total extension of the bar

The ultimate stress for a hollow steel column which carries an axial load of 1.9 MN is 480 N/mm². If the external diameter of the column is 200 mm, determine the internal diameter. Take the factor of safety as 3. 2. An axial pull of 35,000 N is acting on a bar consisting of three lengths as shown below. If the Young's modulus is 2.1x10^5 N/mm², determine i) Stresses in each section and ii) Total extension of the bar.
