Determine what pressure a tractor weighing 5.4 tons exerts on the ice if it rests on tracks with a total

Determine what pressure a tractor weighing 5.4 tons exerts on the ice if it rests on tracks with a total area of 1.5 m2. The ice can withstand a pressure of 90 kPa. Can the tractor pass on the ice?

First, you need to convert the mass of the tractor into C units:

5.4 t = 5.4 * 1000 = 5400 kg.

Since the total length of the tracks is 1.5 m ^ 2, there is no need to find the area based on the number of tracks. This is an important point.

p = F / S, where F is the pressure force, S = the area of the tractor tracks

F = m * g

g = 10 N / kg

F = 5400 * 10 = 54000 n.

p = 54000 / 1.5 = 36000 Pa <90000 Pa, which means the tractor can pass on the ice

Answer: 36,000 Pa.
