Question $1\mathrm{.}2.$

Consider Fig. $2,$ where the surface $AB$ is a circular arc with a radius of $2m$ and a width of $3m$

$($into the paper$).$ The distance from $A$ to the free surface is $2\mathrm{.}4m.$

a$.$ Determine the magnitude, direction, and line of action of the vertical component of the

hydrostatic force acting on the curved surface $AB.$

b$.$ Determine the magnitude, direction, and line of action of the horizontal component of the

hydrostatic force acting on the curved surface $AB.$

c$.$ Determine the resultant hydrostatic force acting the curved surface AB$.$
