If your accelerator gets stuck down, do the following:
Shift to neutral.
Apply the brakes.
Keep your eyes on the road and look for a way out.
Warn other drivers by blinking and flashing your hazard lights.
Try to drive the car safely off the road.
Turn off the ignition when you no longer need to change direction.
Answer:
Explanation:
Given that:
Torque T = 2300 lb - ft
Bending moment M = 1500 lb - ft
axial thrust P = 2500 lb
yield points for tension σY= 100 ksi
yield points for shear τY = 50 ksi
Using maximum-shear-stress theory
where;
where;
Let say :
Then :
According to trial and error;
c = 0.75057 in
Replacing c into equation (1)
The required diameter d = 2c
d = 1.50 in or 0.125 ft
Answer:Report writing consists of the history and facts of a project or of any kind of event. It is useful to record past history and an overall summary of decisions. Report writing helps to solve problems as a path. Writing a report will guide you in a way that will modernize details of the improvements and upcoming plans.
Answer:
a) The proportional limit is 2.99MPa.
b) The modulus of elasticity is 0.427GPa.
C) The poisson´s ratio is 0.021
Explanation:
a) The proportional limit is the maximum stress for wich a tension bar stops acting as a linear material in a stress-strain curve. So this stress can be obtained as:
b) The modulus of elasticity E is the proportion between the strain and the stress in the linear section of the stress-strain curve.
The strain in for the proportional limit is:
Therefore:
c) The Poisson´s ratio is the negative proportion between the transverse strain and axial strain.
In this case, the transverse strain is:
So the poisson´s ratio is:
Answer:
The outer surface temperature is 196.2 C which is lower than 200 C thus TBC layer of 0.028 m thickness will be sufficient to prevent fire hazard.
