A temporary lighting tower stands on four identical footplates. All four footplates are in contact with a level protective floor, and the total force of 9600 N is shared equally between them. Each footplate has an area of 80 cm2.
The floor can withstand a maximum pressure of 2.5 × 105 Pa without being damaged.
Calculate the pressure exerted on the floor by each footplate.
Explain whether the lighting tower can be used without damaging the floor.
