An suv h as a mass given by m = 950 kg. assuming this suv has four tires, find the area each tire on the road íf the pressure in each tire is 35 psi (lb./in^2) (use 1 n/m^2 = 1.45 x10^-4 ib./in^2)

The rigid beam is supported by the three suspender bars. bars ab and ef are made of aluminum and bar cd is made of steel. if each bar has a cross-sectional area of 450 mm2, determine the maximum value of p if the allowable stress is (σallow)st = 200 mpa for the steel and ( σallow)al = 150 mpa for the aluminum. est = 200 gpa and eal = 70 gpa.
