A solid steel shaft in a rolling mill transmits 20 kW of power at 2 Hz. Determine the smallest safe diameter of the shaft if the shear stress τ w is not to exceed 40 MPa and the angle of twist θis limited to 6°in a length of 3 m. Use G = 83 GPa. Solution Applying Eq. (3.6a) to determine the torque:

Saws (Horizontal and Vertical Band Saw)

Vertical Band Saw Vertical band saws, also known as contour saws, perform metal removal jobs that save time and material. Large sheets and bars of material can be cut to size or shape without creating too many chips in a short period of time. Most materials, from wood and plastics to aluminum and steel, can be cut on the two band saws in the shop.


WIND TUNNEL EXPERIMENTAL PROCEDURE

The Clark Y-14 airfoil profile is unusual in that its lower surface is straight and is taken as its chord line. The angle of attack can consequently be checked with an inclinometer contacting the lower surface. The lift, drag, and pitching forces on the airfoil can be calculated from a force balance measurements of the axial force A', normal ...


Introduction to Milling Tools and Their Application

Ball end mills produce a radius at the bottom of pockets and slots. Ball end mills are used for contour milling, shallow slotting, contour milling and pocketing applications. Flutes Spiral-shaped cutting edges are cut into the side of the end mill to provide a path for chips to escape when an end mill is down in a slot or a pocket.

Vertical Milling Machine - Yale

The vertical milling machine is a precision tool used for shaping and fabrication by the removal of stock typically from metallic work pieces. Plastics and other materials can also be machined on the mill depending upon tooling and material. Mill controls may be manually operated, computer numerical controlled (CNC), or a combination of both.
