Answer:
8100 lbin²
Explanation:
Moment or inertia is expressed using the formula
I = mr²
M is the mass of the body
r is the radius of gyration
Given
W = 100lb
r = 9in
Required
Moment of inertia
I = Wr²
I = 100(9)²
I = 100×81
I = 8100lbin²
Hence the moment of inertia about the center of gravity for the rotator is
8100 lbin²
Answer:
The correct answer is C. World Coordinate System
Explanation:
The World Coordinate System has to do with that coordinate system which is fixed in the activities of the CADing. There is a default system in which we can refer to them as soon as we want to manipulate the objects and add new elements.
Answer:
Just think about the number of computerized functions there are in modern automobiles.
Explanation:
If we have 20-ampere circuit breakers. The number of circuits to the larger whole number is: 13.
<h3>Number of circuits</h3>
Receptacles on a single strap= 180 VA each.
Hence,
VA of the circuit=(Volts x Amperes)/One receptacle
Let plug in the formula
VA of the circuit=(120 volts x 20 amperes)/180 VA
VA of the circuit= 2,400 VA (circuit)/180 VA
VA of the circuit = 13 circuits
Therefore the number of circuits to the larger whole number is: 13.
