A set of bookshelves rests on a hard floor surface on four legs, each having a cross-sectional dimension of 3.0 x 4.1 in contact with the floor. The total mass of the shelves plus the books stacked on them is 266 kg.

Calculate the pressure in pascals exerted by the shelf footings on the surface.

Hello. Everyone in this question we asked calculate depression of pascal's When we have kg of mass and contact With an area of 3.0", times 4.1 pressure. Did you go to the forest divided by the area in the force is equal to M times G where M is the mask And G is the acceleration due to gravity, which is 9.8 meters per second square. But for the force And our kilograms Times 9.8 meters per second squared. And this will give us 2606 0. telegrams times meters per second squared. For the area We're gonna get three Times 4. inches And we need to convert to meters but we have 39 in one m and this is square And this will give us 0. 95 later squared. But for the pressure Left 2606 0.8 kilograms times meters per second squared, divide by four. I'm 0.09 five meter square. And this will give us 6551 . Pascal. Thanks for watching my video and I hope it was helpful
