I'm pretty sure its D. Both B. and C.
Answer:
(A) Strain = 0.0012
(b) Stress
(c) Young's modulus
Explanation:
Mass of the rock m = 75 kg
So weight of the rock
Length of the rope l = 18 m
Diameter of the rope d = 11 mm
Change in length of rope
So radius r = 5.5 mm = 0.0055 m
Cross sectional area
(a) Strain is equal to ratio change in length to original length
So strain
(b) Stress
(c) Young's modulus is equal to ratio of stress and strain
So young's modulus
Answer:
1 l = 1000 cc so 1 ml = 1 cc
this is the volume
There is a basic difference, because mass is the actual amount of material contained in a body and is measuredin kg, gm, etc. Whereas weight is the force exerted by the gravity on that object mg. Note that mass is independent of everything but weight is different on the earth
Answer: L.M = 34.69
Area of the bar = 25835m^2
Explanation: To design a bar that can withstand temperature at 773K for 10years, we need to calculate and know:
1) the Larson Miller value
2) rupture time
3) creep rate
4) stress and load.
