a) The sizes of punch and blanking are equivalent to its diameters. The blanking die diameter is Db = 65 mm
Diameter of the blanking punch is,
dpunch = Db - 2c
Here, c = Ac (thickness)
For aluminium, Ac = 0.06
c = (0.06) (3.2 mm) = 0.192 mm
dpunch = (65 mm) - 2 (0.192 mm)
= 64.616 mm
b) The diameter of the punching punch is equivalent to the interior diameter of the washer.
Thus, diameter of the punching die is, Dh = 30 mm
Diameter of the punching die is,
ddie = Dh + 2c
= (30 mm) + 2 (0.192)
= 30.384 mm
Answer:
a metal and a nonmetal element
Explanation:
Answer:
They have the same mass
Explanation:
The two blocks have the same mass. Mass is the quantity of matter contained in a substance. Therefore, the two bodies have the same mass.
The weight is a measure of mass and gravity. The gravity on earth differs from that on the moon. Therefore, the two bodies have different weights.
Their volume is also different since one body is larger than the other. Therefore, density which is the mass per unit volume will also differ.
Answer:
Three states of matter is liquid, solid and gas.
I haven't learned atoms, I just learned the states in 5th grade.
Answer:
it's the uneven heating of the region's of the troposphere by the sun the sun warms the air at the equator more than the air at the poles. it causes convention currents large scale patterns of winds that move heat and moisture around the globe. as air rises expands and cools water vapor condenses and clouds develop.
