Determine the slope at B and the deflection at C by the moment-area method for the beam shown below. Take E =29000 /2 and i=2500 4.

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

Aturning operation is performed with following conditions: rake angle of 12°, a feed of 0.35 mm/rev, and a depth of cut of 1.1 mm. the work piece is aluminum alloy 6061 with t6 heat treatment (a16061-t6). the resultant chip thickness was measured to be 1.0 mm. estimate the cutting force, fc. use shear stress of 207 mpa and coefficient of friction on the tool face of 0.6.

What is the heat treatment of metals? what is the benefit of it? why and how it's useful? answer in details, do not write by hand.
