Below, a vertical plate is submerged in water. Compute the hydrostatic force against one side of the plate. Use 9.8 m/s² to approximate gravitational acceleration. 3 m 5 m 12 m

A dam 30.5m long retains 8 m of fresh water and is inclined at an angle of 60 degrees. Calculate the magnitude of the resultant force on the dam and the location of the center of pressure.

A passenger is standing on a scale in an elevator. The building has a height of 500 feet, the passenger has a mass of 80 kg, and the scale has a mass of 7 kg. The scale sits on the floor of the elevator. (It is an Otis elevator, so we will label it as "O" so as not to confuse its forces with those caused by the earth.) You may take g = 10 N/kg. For doing this problem it might be useful to start by drawing free-body diagrams for the passenger and the scale.Consider the vertical forces acting on the passenger and the scale WE→P: The force of the earth pulling down on the passenger (weight). WE→S: The force of the earth pulling down on the scale (weight). NP→S: The force of the passenger pushing down on the scale (normal). NS→P: The force of the scale pushing up on the passenger (normal). NO→S: The force of the elevator pushing up on the scale (normal). NO→P: The force of the elevator pushing up on the passenger (normal) a) While it is accelerating downward, which of the forces in your…

For a gate having quadrant shape of radius 4.5 m carrying water. What will be the resultant force for a length of 3.5 m of the gate? Is there any effect for the length of gate in the resultant force?

Please solve this question in handwriting. Again please in writing.

find the altitude where the density is 0.001988 slug/ft3

A cylinder (diameter 4 m) of weight 50 kN is placed on the bottom of the tank as shown and oil and water is poured in left and right side of tank respectively. Magnitude of horizontal force at centre that should be applied on cylinder so that it does not roll is (for unit length) kN. 64m Oil S=0.7 1.2 m Water S=1 0.7m

Please help me answer this question. Please use your handwriting so that I can understand it more. please help me. thank you very much
