Answer:
Answer for the question :
"the two boxcars A and B have a weight of 20 000 Ib and 30 000 Ib, respectively. If they coast freely down the incline when the brakes are applied to all the wheels of car A causing it to skid, determine the force in the coupling C between the two cars. The coefficient of kinetic friction between the wheels of A and the tracks is μk=0.5. The wheels of car B are free to roll. Neglect their mass in calculation."
is explained in the attachment.

Answer:
Current Relative Humidity is 29.623
Given:
Current Temperature, 
Dew point temperature, 
Solution:
Now, in order to calculate the Relative Humidity, RH, we use the given formula:

where
a = 17.625
b = 237.7
Now, using the above formula and given values:




On solving the above eqn, we get:
RH = 29.623
True
Explanation:
three point bending is better than tensile for evaluating the strength of ceramics. it is got a positive benefit to tensile for evaluating the strength of ceramics.
