The wrench blanks, and the final wrench produced with the CNC machine, will be made from 6061-T6 aluminum alloy. With a factor of safety of 2, determine (i) the maximum force that can be applied to the handle, and (ii) the maximum torque produced by the wrench in tightening a bolt, both before yielding will occur. Draw a FBD of the wrench when you do the calculations.

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

On a average work day more than work place firs are reorted

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.
