Q.1 A simply supported beam of length L is subjected to a varying distributed load sin (3 x / L) Nm-1 where the distance x in measured from the left support. The magnitude of the vertical reaction force in N at the Left support to
SHEAR FORCE:
The alzebric sum of all vertical forces either left side or right side of section is called shear force
Empirical Correlations for Free Convection
Experimental evidence suggests that free convection heat transfer is a function of the following parameters
Free Convection from Vertical Cylinders
Vertical Cylinders If
then the vertical cylinder may be treated as a flat plate with width = πd, and of height L.
Small Diameter Vertical Cylinders If the above criterion can’t be met by small cylinders, then a correction factor F has to be applied to the average heat transfer coefficient as follows (Pr ~ 0.7)
