A thick walled cylinder has a light string
wrapped around its outer radius and rotates
about a horizontal axis. The string then goes
vertically straight up and over a massive
pulley that also rotates about a horizontal
axis, and finally connects to a mass m =
0.900 kg on a rough incline (μk = 0.200) that
is angled at 25.0° to the horizontal.
When the system is released from rest the mass slides down the ramp
a distance of 1.80...

Problem #2: (10 points) Consider a closed, thin-walled, pressurized cylinder of inside radius r, wall thickness t, and length L. The cylinder is subjected to an internal pressure p. The cylinder is also subjected to equal and opposite end torques T, as shown in Figure 1. At any point in the side wall of the cylinder, a two-dimensional coordinate system is established such that x,-axis is in the axial direction of the cylinder and the Xz-axis is in the circumferential...

Question 2 A titanium tube 200mm diameter and 5mm wall thickness is subjected to an internal pressure of 13.5MPa. The tube contains a longitudinal crack along its full length. Assuming that the tube can be approximated by a single edge notched plate subjected to a tensile stress equal to the hoop stress in the tube determine the crack length to cause failure. You may assume that the material fracture toughness is 55 MPavm. Please provide...
