A 2-in.-diameter standard-weight steel pipe is used as an axially loaded column. Calculate the allowable axial compressive load using Euler's formula and a factor of safety of 4.
The pipe column is 84 in. long and is fixed at one end and pin-connected at the other end. Assume the proportional limit =34 ksi.

A car accelerates from rest along a straight section of road. It starts at position s = 150 m and reaches a speed of 20 m/s at position s = 200 m. It is proposed that this acceleration, a, can be modelled as being a function of position, s, in the fo..
a block is subjected to a triaxial stress of 16 mpa on the YZ , - 11 mpa on the XZ face & 52 mpa along XY face. if these stresses produce a strain in the x - direction of 49.2 x 10^-6 m/m, what is the poisson's ratio of the block.
