Explanation:
Crank rocker mechanism is formed when the shorter link revolves and the others rock( oscilllates)
Whereas the double rocker mechanism is formed when both the side link rock and the others oscillate.
Crank rocker mechanism can be used to convert rotary motion into oscillatory motion.
Answer:


Explanation:
The distance of the chain would be the product of the dislocation density and the volume of the metal.
Dislocation density = 
Volume of the metal = 



The chain would extend 
Dislocation density = 
Volume of the metal = 


The chain would extend 
Answer:
Q = 424523.22 kw
Explanation:

k = 48.9 W/m - K
c = 0.115 KJ/kg- K


T_∞ = 35 degree celcius
velocity of air stream = 15 m/s
D = 40 cm
L = 200 cm
mass flow rate




solving for h

h = 675.6 kw/m^2K

Q = 675.6*2.513*(285-35)
Q = 424523.22 kw
