Expert Solution & Answer
To determine
What are the major properties required of cutting-tool materials? Why?
Explanation of Solution
A cutting-tool material should have the below attributes:-
Hot hardness
Wear resistance coupled with hardness and strength of the tool stay intact at the temperatures experienced in machining operations. This property is responsible for making sure that the tool would not go through any plastic deformation. That is how it retains its sharpness and forms both.
Toughness and strength of impact
In interfered cutting tasks or forces like milling, and then turning a splined shaft on a lathe, the forces of impact on the tools is experienced time and again. This is because of vibration and chatter amid machining. But this neither chip nor break the tool.
Thermal shock resistance
To bear the fast temperature cycling, as experienced in interfered cutting.
Wear resistance
With the goal that a long-enough tool life is acquired before substituting becomes inevitable.
Chemical stability and inactiveness
Concerning the workpiece material, to evade or limit any unfavorable reactions, adhesion, and tool–chip diffusion which may fasten the wear of the tool.

A linear system is one that satisfies the principle of superposition. In other words, if an input u₁
yields the output y₁, and an input u2 yields the output y2, the system is said to be linear if a com-
bination of the inputs u = u₁ + u2 yield the sum of the outputs y = y1 + y2.
Using this fact, determine the output y(t) of the following linear system:

The manometer fluid in the figure given below is mercury where D = 3 in and h = 1 in. Estimate the volume flow in the tube (ft3/s) if the flowing fluid is gasoline at 20°C and 1 atm. The density of mercury and gasoline are 26.34 slug/ft3 and 1.32 slug/ft3 respectively. The gravitational force is 32.2 ft/s2.
Using the Bernoulli equation to find the general solution. If an initial condition is given, find
the particular solution.
