1.A driver in a vehicletraveling 40 mph shifts his eyes from right to left and focuses ona child about to dart across the street. estimate the distance infeet the vehicle travels as the driver's eye shift andfixate?
2.A beam of rectangular cross section 300mm by 100mm sitsupright and has a moment of inertia of 225 X 10-6m4 and a max bending moment of 67.5KNm. Determine themax value of bending stress in the beam.
3.Determine the young's modulus for a metal whose elasic limit isone half of its UTS. The material has a strain of 0.002 at theelastc limit and a gauge length of 50mm. The UTS of the metal is300 MPa. The metal sample has a diameter of 20mm.
