1.

stick (2.5 RgA stick of square cross-section (5 cm x 5 cm) and length 4mweighs 2.5 kg is in equilibrium as shown in the figure below.Determine its angle of inclination in degree) in equilibriumwhen the water surface is 1 m above the hinge1m

Answer»

The length of the rod is 4m.

The depth of water is 1m

Then tan Ѳ = Depth of water/ length of rod

tan Ѳ = ¼

Ѳ = tan-1(1/4)

Then Inclination angle (Ѳ) = tan-1(1/4)
