Fig. 1.1 shows a wooden bench of weight 2000 N. [Figure 1.1]

1. (a)Each of the two supports has an area of 0.040m² in contact with the ground. Calculate the pressure on the ground due to the bench. pressure =[2]
2. (b)(i)The centre of mass of the bench is 1.1 m from the left-hand end of the bench and 0.24 m from the front. Suggest one reason why the centre of mass is in this position.[2]
3. (b)(ii)There is a force exerted vertically downwards from the point P shown in Fig. 1.1. Calculate the maximum force that can be exerted vertically downwards at P without the bench rotating about the point Q shown in Fig. 1.1. maximum force =[3]
