____ grinders are used to grind diameters, shoulders, and faces much like the lathe is used for turning, facing, and boring operations.
Answer:
Cylindrical
Explanation:
A cylindrical grinder is a tool for shaping the exterior of an item. Although cylindrical grinders may produce a wide range of forms, the item must have a central axis of rotation. Shapes such as cylinders, ellipses, cams, and crankshafts are examples of this. Cylindrical grinding machines are specialized grinding machines that are used to process cylinders, rods, and similar workpieces. The cylinders revolve in one direction between two centers, while the grinding wheel or wheels are close together and rotate in the other direction.
A ball is thrown vertically up with a velocity of 80 ft/sec at the edge of a 200-ft cliff. Calculate the height h to which the ball rises and the total time t after release for the ball to reach the bottom of the cliff. Neglect air resistance and take the downward acceleration to be 32.2 ft/sec.
Answer:
y = ut + [tex]\frac{1}{2}[/tex][tex]at^{2}[/tex] , y = 80t - [tex]\frac{1}{2}[/tex][tex]32.2t^{2}[/tex]
for y = -200 ft,
-200 = 80t - [tex]16.1t^{2}[/tex] or [tex]16.1t^{2}[/tex] - 80t - 200 = 0
t = 80 ± [tex]\frac{\sqrt{80^{2} + 4(16.1)(200) }}{2(16.1)}[/tex] = 6.80 sec. ( or - 1.83 s)
For y = 0, [tex]u^{2}[/tex] = [tex]u_{o}^{2}[/tex] + 2ay, y = h = [tex]\frac{0-80^{2} }{-2(32.2)}[/tex]

Nonshielded cable with a 1.5-inch diameter should have a minimum bending radius of
A. 1.5 in.
B. 12.0 in.
C. 3.0 in
D. 18.0 in.
Answer:
c is the answer because we have to double the number
A non-shielded cable should have a 3.0 in minimum bending radius and a 1.5 in maximum diameter. As a result, choice (C) is the right response.
What are shielded and unshielded cable?Based on their architecture, these cables are typically divided into two classes: shielded cables and unshielded cables.
Shielded twisted pair (STP) cable is another name for shielded cables. It has distinct wire pairs that are foil-wrapped. To offer double protection, these pairs are wrapped one more time. The shielding aids in preventing EMI and other technical problems that can jeopardize the signal integrity.
Unshielded cable, also known as unshielded twisted pair cable (UTP), is a type of cable in which the individual wire pairs are simply wrapped in foil without any additional layers of protection. Office settings with low traffic are best suited for unshielded wires.
Hence option (C) is accurate.

OA. 9.00 inches.
On the print you would expect the pitch diameter of the gear to be 9.00 inches. Option A is right.
How to solve for the diameterGear ratio = 1/3
This is solved as number of teeth on pinion / teeth on gear
= Np/Ng
The pitch diameter = 1.5 x 2
= 3
Diametral pitch = 12
NP = 3 x 12 = 36

A transformer has 300,000 windings in its primary coil and uses 12,000V AC input. (4 points) How many windings would be needed to produce at output of 110V AC
Answer:
2750
Explanation:
The number of windings and the voltage are proportional.
__
Let n represent the number of windings to produce 110 Vac. Then the proportion is ...
n/110 = 300,000/12,000
n = 110(300/12) = 2750 . . . . multiply by 110
