Problem 1
1: Leaming Outcome #2
A uniform body A having a width b into the paper is in static equilibrium when piloted about hinge O.
The shape is a quarter of a circle with radius R. Neglect the atmospheric pressure. 7-9790H 1².
(a) Find the hydrostatic horizontal and vertical forces acting on the body A
(b) Find the weight of the body A
Hints for part (b): (1) the centroid of a quarter of a circular area is located a horizontal and a vertical
distance of 4R/(3x) from the center of the circle. R is the radius of the circle; (I) There are unknown forces
at hinge O (which we don't need to find).
