A cannister for a hydraulic fluid debris filter is shown in the cross-sectional diagram below. The cannister wall is a cylindrical tube which is compressed between two rigid heads - by 4 bolts (where only 2 are shown on the cross-sectional diagram below). The cannister wall is made of aluminum. The operating pressure is 1,500 psig and the pressure is 0 psig when not operating under static conditions. The bolts are made of 3/8-24 fully threaded rod (in US Customary Units) with standard nuts on both ends. The bolts are initially torqued under static conditions to a preload value of 4,000 lb.
Find:
The preload stress on the bolts - assuming uniform load sharing of all 4 bolts under static conditions.
The preload stress on the cylinder wall under static conditions.
The operating stress on the bolts - assuming uniform load sharing of all 4 bolts under operating conditions with the 1,500 psig internal cylinder pressure.
The operating stress on the cylinder wall under operating conditions with the 1,500 psig internal cylinder pressure.
