Lab report

Determine what the material is, based on the data. Discuss industry uses of this material. What would it be suited for? What would it NOT be suited for? Look at all aspects, not just uses specific to your major.

Discuss the “general implications” of the results obtained, suitability, concerns, etc. Then address the specific situation, state if the sample is suitable for the intended purpose, and what you can do if it does not meet the specification.

Situation 1: Select the size of a hollow steel shaft necessary to transmit 150 hp at 250 rpm without exceeding an allowable shear stress of 7.4 ksi, or having a relative angle of twist beyond an allowable value of 0.35° per 1-ft length. The ratio k = di/do = 0.75. Assume the material of the shaft is the material tested in the experiment.

Situation 2: Select the size of a solid shaft necessary to transmit 260 kW at 300 rpm without per meter length of the shaft. Assume the shaft is the same material used in the experiment. 5.0 Sources of Error

Report any sources of error that could have occurred in the laboratory and/or in breaking down the data. Some sources of error exist for every lab (example – human errors, inexperienced technicians, etc.). If you adjust an obvious value that is wrong, or threw a bad point out, report it here, state how you found it and how/why you corrected it.

You can do this in bullet form and number 5.1, 5.2, 5.3, etc. It is easier to write this way. Then you don’t have to connect all your sentences in paragraph form. If you do this, always include a lead in sentence under 5.0.
