$-$ Do NOT draw an effective force for any distributed pressures $-$ you must draw these out as distributed loads

$-$ For all distributed loads, indicate the magnitude of the pressure at the end points.

$-$ DO NOT SOLVE ANY STATIC EQUILIBRIUM CALCULATIONS. You are simply providing the FBD$!$ Do not neglect weight unless specified.

$($a$)$ FBD of the cone floating in water

back a reservoir of water

$($c$)$ FBD of the gate bolted onto the lower left. Neglect the weight of the gate. Density of oil is $\backslash (900\backslash$mathrm$\{$~kg$\}/\backslash$mathrm$\{$m$\}^\{3\}\backslash )$

$($d$)$ FBD of the vertical gate. Moment $\backslash ($ M $\backslash )$ is being applied to the gate at point B $.$ Density of salt water is $\backslash (1050\backslash$mathrm$\{$~kg$\}/\backslash$mathrm$\{$m$\}^\{3\}\backslash ).$ Ignore the small length of the gate beneath point $\backslash ($ A $\backslash )$
