An MgO component must not fail when a tensile stress of 30 MPa is applied. Determine the maximum allowable surface crack length for a loading/geometry with geometric factor of 1.92 Assume the major axis of the elliptical flaw is normal to the tensile loading axis.

What precautions should you take to prevent injuries when dealing with heavy loads?

Calculate the bore of a cylinder that has a stroke of 18 inches and an extension time of 6 seconds at a flow rate of 4 gal/min.

The flow rate of air through a through a pipe is 0.02 m5/s. a pitot static tube is placed in the flow. the radius of the pitot static tube is 1 mm. assuming the flow to be steady and the air to be at 300k, calculate the difference in total and static pressure if the diameter of the pipe is: (a) d 0.1 m d 0.05 m (c) d 0.01 m
