Formula
The maximum permissible point load at-mid-span may be obtained from the formula
P=  ½ X U X C
Where P = maximum permissible point load in kgs. at mid-span. 
U = maximum permissible uniformly distributed load in kg per running meter.
S = the particular free span in meter
Free Span Exceeding 16ft. are not recommended.
