Otis Boykin is the answer.
Answer:
Forced vibrations and self-generated vibrations
Explanation:
Forced vibration is caused due to the motion of the cutting operation itself it is common in operations that have interrupted cutting like milling.
The size of the chips are related to self-generated vibrations. If larger chips are formed this means higher depth of cut is given. If smaller chips are formed this means lower depth of cut is given. When we give excess depth of cut then self-generated vibrations are produced.
Answer:
The change in internal energy of the engine is -1,571 Joules.
Explanation:
Change in internal energy (∆U) = energy output (U2) - energy generated (U1)
U1 is the energy generated = 2203 Joules
U2 is the energy output = 632 Joules
Change in internal energy (∆U) = 632 - 2203 = -1,571 Joules
Answer:


Explanation:

Mechanical advantage is will be the ratio of the distances from the wheel axle of the forces.

The ideal mechanical advantage of the system is
.
The moment in the system is conserved so moment about the wheel axle is

The required effort force is
.
