Answer:
Explanation:
(a) Swirl tangential speed = 3 x MPS ( mean piston speed)
= 3 x 420.76 inch/sec = 280.51 [ft/sec]
The other detailed steps is as shown in the attached file
Answer:
The question is incomplete, the complete question is:
Which of the following is not a reason to give yourself extra "cushion" when driving?
A. Poor visibility B. Poor road conditions C. Inclement weather D. None of these.
The correct answer is D. None of these.
Explanation:
All the options are not reasons to give yourself an extra cushion when driving, rather they are reasons that are not favorable to driving at all.
A cushion is a certain amount of distance you are supposed to keep between you and the car in front of you to allow easy maneuvering in any condition.
A typical cushion is 3 seconds between you and the car in front of you, in less than perfect conditions like bad weather or poor road conditions an additional second must be added to it.

Answer:
a) 116.67 MPa
b) 368.85 GPa
c) -1.0122 *10^{-4}
Explanation:
Given data:
length of bar is 1.50 m
total elongation in bar = 1.22 mm
axial load = 35.0 kN
cross section dimension = 6 by 50 mm
proportional limit = 300 MPa
a) AXIAL STRESS
Stress =force/area
b) modulus of elasticity
where E = modulus of elasticity
E = 36.8.85 GPa
c)
where is poisson's ration= 0.32
Answer:
15.8529 kW
Explanation:
Rate of heat loss = 60000 Btu/h
Internal heat gain = 6000 Btu/h
Rate of heat required to be supplied
Converting 54000 Btu/h to kW (kJ/s)
1 Btu = 1.05506 kJ
1 h = 3600 s
∴ Required rated power of these heaters is 15.8529 kW
