Question

calculate the pressure produced by applying 56N force on a flat surface having a width of 160cm and a length measuring 5m

Answer 1

Answer: 7.375Nm-2

Explanation:

                      pressure=thrust/area

                      p=59/1.6*5  = 7.375

Answer 2

Answer:

The answer pressure = 7 Pa

Explanation:

length=5m=5 x 100= 500 cm

therefore, area =500 x 60 =30000 cm^2=3 m^2

pressure=45/3=15 N/m^2

pressure = force/area

area = length*breadth

area = 160*500

area = 80000cm²

area = 8m² (1m²= 10000cm²)

pressure = 56/8 Pa

pressure = 7 Pa
