Since the above 2 questions are answered correctly, below is the explanation: We know, a) We know, Pressure(P)=Force(F)4×Area(A)......(since 4 tires are in contact)Here, F=mg=1450×9.81 N=14224.5 NP=38.5 lb/in2= 38.5 psi=38.5×6894.76......(1 psi=6894.76 Nm2)=265448.26 Nm2Hence, 4A=14224.5265448.26=0.05358Therefore, A=0.053584A=0.0134 m2 b) By looking at the formula, it is clear that pressure is inversely proportional to the Contact Area. Hence when gauge pressure increases, the Contact area decreases.Referring to the same formula, in this part, F=14224.5 N......givenA=105×10-4 m2Therefore, P=F4A=14224.54×105×10-4=338678.57 Nm2=338678.576894.76psiGauge Pressure(P)=49.12 psi
