Answer:
Tension in cable BE= 196.2 N
Reactions A and D both are 73.575 N
Explanation:
The free body diagram is as attached sketch. At equilibrium, sum of forces along y axis will be 0 hence
hence
Therefore, tension in the cable,
Taking moments about point A, with clockwise moments as positive while anticlockwise moments as negative then
Similarly,
Therefore, both reactions at A and D are 73.575 N
Answer:
Explanation:
Given data:
carbon concentration = 0.54%
from the relation given below calculate the time required to achieve concentration at 6.00 mm from surface
D considered constant
here, x POSITION FROM SURFACE, t is time required to achieve concentration
