Question

A ceremic tile measuring 50cm x 50cm has been designed to bear a pressure of 40N/m square. Will it withstand a force of 5N.

Answer 1

Given, 

Side of tile = 50 cm  

First we change it to Metre 

We know,  

1 m = 100 cm 

100 cm = 1 m 

1 cm = 1 / 100 m 

50 cm = 50 / 100 m  

50 cm = 1 / 2 m 

50 cm = 0.5 m 

Area of tile = (side)²

= 0.5 x 0.5 

Area of  tile  = 0.25 m² 

It is given that tile can carry a pressure of 200 N/m². If the force applied by this pressure is F, 

F = Pressure x Area to tile 

F = 200 x 0.25 

F = 2 x  25 

F =  50 N 

Hence, It  can withstand any force less than 50 N.
