Question

Calculate the pressure exerted on the floor by the camel if the weight of the camel is 60 kg.
Assume that the area of contact of each feet is 6cm by 25 cm. (Take 1 kg weight equal to 10
Newtons.)

Answer 1

Explanation:

For the given question we can use the formula, F=mgF=mg where F is the gravitational force, m is the mass of the body and g is the acceleration due to gravity.

We know that, P=FAP=FA where P is the pressure exerted by a body, F is the force acting on the body and A is the area where the force acts.

We are given that a boy is standing on both feet on the floor. The weight of the boy is 40kg and the area of contact of each shoe is 6 cm by 25 cm .

We know that 1kgwt=10N

Hence, 40kg wt can be converted to 40×10=400N40×10=400N

The area of contact of each shoe=6cm×25cm=(6100×25100)m2=151000m26cm×25cm=(6100×25100)m2=151000m2

Hence, total area of contact is (151000×2)m2=3100m2(151000×2)m2=3100m2

We know that

P=FAP=FA

⇒P=4003/100=400003=403=13.33
