Period 3 HW solutions
Profile milling generally involves the milling of the outside periphery of a flat part. Problems In an orthogonal cutting operation, the tool has a rake angle = 15°. The chip thickness before the cut = mm and the cut yields a deformed chip thickness = mm. Calculate (a) the shear plane angle and (b) the shear strain for the operation. Solution: (a) r = t o /t c = / = 0 ...

How Do Wind Turbines Work? | Department of Energy
A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.

Metal forming processes
Hammers: Hammers operate by applying an impact loading on the work piece. This is also called as drop hammer, owing to the means of delivering impact energy. When the upper die strikes the work piece, the impact energy applied causes the part to take the form of the die cavity. Sometimes, several blows of the hammer are required to achieve

concentrations of thermal energy near the surface of the Earth that can be used as an energy resource. Heat is transferred from the deeper portions of the Earth by conduction through rocks, by the movement of hot, deep rock toward the surface, and by deep circulation of water. Most hightemperature geothermal resources are associated with concentrations of heat caused by the movement of magma ...

milling using hammer mill and packaging. Based on the theory that thickness of materials is among the factors controlling drying rate (Mohammed, 2009), thickness of the yam was reduced by 5 mm. In practice 20 mm thickness yam is used. This was reduced to 15 mm. In addition, the shape of the yam was changed from conventional cylinder to diagonal.
