2. A water gate is 3m high and 1m wide. What is the force acting on the lower stay when the top of the gate is 4m below the surface of water? 4m h' = 2m 3m

A steel pipe will be installed and extends almost from one wall to another.  The walls are 62.2 m apart. The pipe has a steel elbow at each end, and the design length of the pipe plus elbows is 61.5 m at 24.3 ºC.  A clearance of 210 mm has to be left at either end of the pipe, for bracing to the wall. If the pipe is to carry steam at 375 ºC.  (a) will it fit?  (b) At what temperature will it just fit? 404 ºC

just give a simple solution

14-17. A vertical rectangular gate 2m wide and 3 m high is submerged in water with its top edge flushed With the water surface. Find the following: • The value of the maximum force, Facting on center of pressure • The value of the eccentricity • The location of Force , F below the water surface • The magnitude of the maximum pressure
