The epicyclic gear train consists of the sun gear a which is in mesh with the planet gear b. this gear has an inner hub c which is fixed to b and in mesh with the fixed ring gear r. the connecting link de pinned to b and c is rotating at ωde = 18 rad/s about the pin at e.

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.

When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested? a. parallel b. control c. series d. line
