Question 14

A modular walkway rests on five identical pads on level ground. The total weight of the walkway and anything on it is shared equally between the pads. Each pad has a contact area of 0.025 m2. The ground can withstand a pressure of up to 80 000 Pa80\,000\ \mathrm{Pa}80000 Pa.

What is the greatest total weight that the walkway and its load can have?
