Answer:
The Force on one side of the pate is 58800N.
Step-by-step explanation:
The base of triangle is given as b=2m
The height of triangle is given as h=3m
Gravitational Acceleration is given as g=9.8 m/s^2
The density of water is given as ρ =1000 kg/m3
Now for a rectangular strip DE as shown in the attached figure, of width dy and length x is considered for which the area is
The area is given as
Also for this the pressure at depth y is given as
As the triangles are similar so
Now the differential force is given as
Now for the total force, the integral for 0 to h=3 m is given as
So the Force on one side of the pate is 58800N.
