Problem: A beam of rectangular cross section 200mm deep and 100 mm wide. If the beam is 3 long, simply supported at either end and carries point loads as shown in figure.
(a) Calculate the maximum bending moment.
(b) Calculate the maximum stress in the beam.
(c) At the point of maximum stress sketch a graph of the stress distribution through the thickness of the beam, indicating which tensile and comprehensive stresses are.
(d) Determine the dimensions of the cross section which will minimize the maximum stress value if:
Show the dimensions of the proposed beam cross section with the aid of a sketch.
(e) Determine the percentage reduction of the maximum stress value when the new cross section is used.
The pressure in an automobile tire depends on the temperature of the air in the tire. When the air temperature is 25°C, the pressure gage reads 210 kPa. If the volume of the tire is 0.025 m3, determine the pressure rise in the tire when the air tempe..
