I have a drilling machine that needs to be analyzed. I need to know the following things about the drill to know if I should buy. I need this analysis to be correct to convince my friend to buy it.

Load estimation: Describe all the worst-case loading conditions that you can think of. Describe the nominal operating loading condition as well. Consider both static and dynamic loads. Defend your decisions.

Failure modes: A failure mode is a description of a failure that is likely

to occur in a component or assembly under a specific loading scenario. Describe all the different ways in which the drill could undergo mechanical failure. Consider failures related to strength, stiffness, stability, or other effects. Consider all load types: tension, compression, shear, bending, and torsion, and combinations. You must describe at least two failure modes for each part analyzed.

Load analysis: identify the worst case loading

scenario in the most likely failure mode. This is the condition under which you will complete the remainder of the analysis. For this step, draw a free body diagram, consider both static and dynamic loads. To do this well, you will require characterization of the most severe usage scenarios, power source(s), losses, and loads. Clearly list all assumptions made.

Static failure analysis: Perform a static failure analysis on the part,

using the failure theories. The outcome of the analysis should be

an answer to the following question: “Under the chosen failure mode and loads, will the part fail under the static loads? If yes, at what load? If not, what is the factor of safety guarding against failure?”

Dynamic failure analysis: Perform a dynamic failure analysis on

the part, using the failure theories. The outcome of the analysis

should be an answer to the following question: “Under the chosen failure mode and loads, will the part fail under dynamic loads? If yes, under which conditions of mean and amplitude loads? If not, what is the factor of safety guarding

against failure?”

More information will be provided about the drilling machine after finding the right freelancer.
