If you use the same Raspberry Pi to do waveform generation and waveform recognition at the same time, you might generate a waveform that the frequency keeps changing and get random readings from the MCP3008. Explain why this is the case.

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

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

Shafts are machine elements that are used to a) carry axial loads b) direct shear loads c) transmit power d) rotate at constant speed e) none of the above circular and square shafts subjected to the same torque under the same circum behave a) the same way b) almost the same way
