Questions
An isosceles triangular plate of base 3m and altitude 3m is immersed in oil vertically with its base coinciding with the free surface of the oil of relative density 0.8. Determine the total thrust.
detailed solution
Correct option is C
Area of the plate = 4.5m2 , density of the oil = 0.8×1000=800kg−m−3Depth of the C.G of the plate from free surface is 13.3=1mNow the total thrust on the plate = ( plate area ).( pressure at the C.G of the plate) = 4.5×(800×10×1)=36kNTalk to our academic expert!
