g) An injection mould is setup as shown in Figure below. The pressure applied is 70 MPa and assume that the diameter of runner is 7 mm and length of runner is 500 mm. Calculate the mould-clamping for...
The brake, shown in figure below, is 300 mm in diameter and is actuated by a mechanism that exerts the same force F on each shoe. The shoes are identical an have a face width of 30 mm. The lining is a of ceramic type having a coefficient friction of 0.35 and a pressure limitation of 1.1 MPa. Find the following: (a) Actuating force F. (b) Braking torque capacity
4.A thin-walled cylindrical column carries a weightless arch and is loaded as shown in Figure 4. The column has an internal diameter of 250 mm with a thickness of 2 mm Given: E-200 GPa and 0.3 The answer to each part of the question is to be used for subsequent parts (a)Determine the stresses on the outer surface of the cylinder at points A and B due to (8 marks) (b) Determine the minimum internal pressure p required if the...
A cylindrical bar of ductile cast iron is subjected to reversed
and rotating-bending tests, test results (i.e., S-N
behavior) are shown in Animated Figure 8.21. If the bar diameter is
8.52 mm, determine the maximum cyclic load that may be applied to
ensure that fatigue failure will not occur. Assume a factor of
safety of 2.21 and that the distance between loadbearing points is
55.3 mm.
