A scaffold of mass 50 kg and length 7.0 m is supported in a horizontal position by a vertical cable at each end A window washer of mass 80 kg stands at a point 1.5 m from one end. a What is the tensio?
Koty761
say washer is left of centre, then tension on left =((80*5.5/7)+25)=87.86kg
tension on right=((80*1.5/7)+25)=42.14kg

This is not always true. High velocity pumps can be found in horizontal configurations too. It all depends on the application (sometimes the manufacturer) whether it will be a horizontal of vertical pump.
In the 5G position for welding pipe the pipe must?
The pipe must be fixed (not rolled) in the horizontal position. With the pipe horizontal, the weld is vertical.

Which is better vertical or horizontal condenser?
Hi.. For only filmwise condensation, horizontal position gives higher condensation coefficent than verical position. In case of condensation with subcooling in a shell and tube heat exchanger, condensation coefficient is higher with horizontal postion while subcooling coefficient is higher with vertical position. kal....
