To determine
The three basic categories of material removal process.
Expert Solution & Answer

Explanation of Solution
The tree basic categories of material removal process are conventional machining, abrasive process and non-traditional process.
In conventional machining the materials are mechanically cut by sharp cutting tools to get the required shape. In abrasive process hard, abrasive particles are used to remove material mechanically. In non-traditional method tools except sharp cutting tools, abrasive particles and energy forms like

A viscoelastic column is made of a material with a creep compliance of
D(t)= 0.75+0.5log10t+0.18(log10t)^2 GPA^-1
for t in s. If a constant compressive stress of σ0 = –100 MPa is applied at t = 0, how long will it take (= t1/2) for the height of the column to decrease to ½ its original value? Note: You will obtain multiple answers for this problem! One makes sense physically and one does not.
A group of 23 power transistors, dissipating 2 W each, are to be cooled by attaching them to a black-anodized square aluminum plate and mounting the plate on the wall of a room at 30°C. The emissivity of the transistor and the plate surfaces is 0.9. Assuming the heat transfer from the back side of the plate to be negligible and the temperature of the surrounding surfaces to be the same as the air temperature of the room, determine the length of the square plate if the average surface temperature of the plate is not to exceed 50°C. Start the iteration process with an initial guess of the size of the plate as 43 cm.
The properties of air at 1 atm and the film temperature of (Ts + T)/2 = (50 + 30)/2 = 40°C are k = 0.02662 W/m·°C, ν = 1.702 × 10–5 m2 /s, Pr = 0.7255, and β = 0.003195 K–1.

A 40-cm-diameter, 127-cm-high cylindrical hot water tank is located in the bathroom of a house maintained at 20°C. The surface
temperature of the tank is measured to be 44°C and its emissivity is 0.4. Taking the surrounding surface temperature to be also 20°C,
determine the rate of heat loss from all surfaces of the tank by natural convection and radiation.
