Question

a truck mass 50,000 kg its tyres exerts pressure of 2,500,000 Pa . the surface area of tyres in contact with ground is ?

Answer 1

Given,mass =50,000kg

Pressure=2,500,000pa

1 bar =1,00,000 pa

Then 2,500,000÷1,00,000=25bar

We know Pressure=Force/Area

Then ,area =Force/Pressure

Now,

Area =50,000÷25=2000cubic metre

Answer 2

Hey there!

Given,

Mass (m) = 50 000 kg

Pressure (P) = 2,500,000 pa

Force (F) = ?

Area (A) = ?

We know,

Force= Mass  * acceleration

         = 50 000 * 10

         = 5 00 000 N

And,

Pressure = Thrust / Area

Area = thrust / pressure

Area = 5,00,000 / 2500000

Area = 5/25

Area = 1/5 sq. unit
