Question

Fig.1 shows a section through a very old bicycle tyre that is made of solid rubber. Fig.1 Fig. 2 The solid rubber tyre exerts a pressure on the ground. i) The weight of the bicycle and rider is 600 N and the total area of the tyres in contact with the road is 30 cm2. Calculate the pressure exerted by the bicycle on the road. ii) One of the solid rubber tyres goes over a small stone, as shown in Fig. 2. Explain how the pressure exerted on the ground changes. 2. A packaging company purchases corrugated cardboard boxes in

Answer 1

pressure = force/area
now, pressure= 600/30
so the pressure is 20

question: how the pressure on the ground changes

answer: the law for force and pressure states that more is the pressure if less is the area and less is the pressure if more is the area

this is why are tyre can go over a small stone
