Part A Choose a tool or a device you can investigate. It must not have any source of power other than the person using it. It must use one or more of the six simple machines. Explain how the tool or device is used. What work does a person do while using it? What kind of motion do we see when it’s used?

Part B
Which simple machines are used in the tool or device?

Part C
What materials are used to make the tool or device? Why did the designers pick those materials?

Part D
Question
Draw the tool or device, and label where the input force is exerted and where the output force is exerted.

Part E
Mechanical advantage is the ratio of output force to input force. Does the tool or device have a mechanical advantage that is greater than 1, equal to 1, or less than 1? Do some research on the Internet or at a library if you aren’t sure.

Part F
Suggest one or more improvements that designers could make to the tool or device.

The air in an automobile tire with a volume of 2.60 ft3 is at 70°f and 21 psig. determine the amount of air that must be added to raise the pressure to the recommended value of 30 psig. assume the atmospheric pressure to be 14.6 psia and the temperature and the volume to remain constant. the gas constant of air is ru = 53.34ft⋅lbflbm⋅r(1 psia144 lbf/ft2) = 0.3704 psia⋅ft3lbm⋅r the amount of air that must be added to raise the pressure is lbm
