Answer:
Pneumatics use easily-compressible gas like air or pure gas. Meanwhile, hydraulics utilize relatively-incompressible liquid media like mineral oil, ethylene glycol, water, synthetic types, or high temperature fire-resistant fluids to make power transmission possible

Answer:
Considering the guidelines of this exercise.
The pieces produced per month are 504 000
The productivity ratio is 75%
Explanation:
To understand this answer we need to analyze the problem. First of all, we can only produce 2 batches of production by the press because we require 3 hours to set it up. So if we rest those 6 hours from the 8 of the shift we get 6, leaving 2 for an incomplete bath. So multiplying 2 batches per day of production by press we obtain 40 batches per day. So, considering we work in this factory for 21 days per month well that makes 40 x 21 making 840 then we multiply the batches for the pieces 840 x 600 obtaining 504000 pieces produced per month. To obtain the productivity ratio we need to divide the standard labor hours meaning 6 by the amount of time worked meaning 8. Obtaining 75% efficiency.
(a) The thermal efficiency of the cycle.
The thermal efficiency of the cycle is given by
NThermal= net work/ heat supplied
NThermal= WNet/QH
=2026.08/4547.82= 44.55%
(b) The backwork ratio:
compressor work/ turbine work
=1760.76/3786.84= 0.465
(c) The net power developed:
WNet= WT-WC
WNet= 3786.84- 1760.76= 2026.08 kW
Answer:
a) 1/2
Explanation:
Overexertion accounted for more than half of all events that resulted in a disabling condition.
Furthermore, 30% of all overexertion cases were reported in the services industry, on the other hand, 25% of injuries resulting from contact with objects and equipment occurred in the manufacturing industry.
The above piece of information is taken from the bureau of labor statistics, Survey of Occupational Injuries and Illnesses
