“Thinking about pleasant things to pass the time” would not promote safety in the shop because it would be taking the focus away from important tasks, which in turn decreases safety.
Answer:
1425.78 N.m
Explanation:
Moments of force is calculated as ;
Moments= Force * distance
M= F*d
The S.I unit for moment of force is Newton-meter (N.m)
Given in the question;
Force = 72 lbs
1 pound = 4.45 N
72 lbs = 4.45 * 72=320.4 N
Distance= 15 ft
1ft= 0.3048 m
15 ft = 15*0.3048 = 4.57 m
d= 4.57 m
M= F*d
M=320.4*4.57 =1425.78 N.m

Answer:
Explanation:
Given data:
length of Steel bolt
Length of aluminium cylinder
Pitch of bolt p = 1mm
Modulus of elasticity of steel E = 215 GPa
Modulus of elasticity of aluminium = 74 GP
Area of bolt
Area of cylinder = 2300 mm^2
n =1
By equilibrium
By the compatibility
Displacement in steel is
Displacement in Aluminium is
from compatibility equation we have
substitute
Stress in Aluminium
