Question

A metal plate 1.25 m x 1.25 m x 6 mm thick and weighting 90 N is placed midway in the 24 mm gap between the two vertical plane surfaces. The Gap is filled with an oil of specific gravity 0.85 and dynamic viscosity 3.0N.s/m². Determine the force required to lift the plate with a constant velocity of 0.15 m/s.​

$\huge\boxed{\fcolorbox{red}{ink}{SOLUTION:}}$

$\huge\boxed{\fcolorbox{purple}{ink}{GIVEN:}}$

• A metal plate 1.25 m x 1.25 m x 6 mm thick

• Weighting 90 N is placed midway in the 24 mm gap between the two vertical plane surfaces.

• The Gap is filled with an oil of specific gravity 0.85

• Dynamic viscosity 3.0N.s/m².

$\huge\boxed{\fcolorbox{pink}{ink}{TO FIND:}}$

• The force required to lift the plate with a constant velocity of 0.15 m/s.

$\huge\fbox\pink{✯Answer✯}$

• By Using the formula to find out force we get answer easily.

• By using Formula we get

▬▬▬▬▬▬▬▬▬▬▬▬
