1. A bar with a diameter of 2.5 cm is subjected to a tensile load of 55 kN. What stress is generated in the bar? 2. The stress that a 1.75 cm diameter bar is subjected to is 361.7 kPa. What load has been applied to the bar? 3. What is the diameter of a bar which is subjected to a load of 90 N and results in 400 kPa of stress? 4. 5. 6. 7. 8. 9. A rectangular bar supports a load of 45 kg. The bar measures 2.3 cm x 4.0 cm. What stress is produced? A full 20 m water tank is supported by 4 concrete posts which have a diameter of 65 cm each. If the mass of the tank itself is 750 kg, how much stress is each support subjected to? If the concrete posts in question #5 have an original length of 0.62m and shorten by 0.78 mm under load, what is the strain? A 3.5 m strut supports a 325 kg compressive load. The strut has a diameter of 70mm and shortens by 1.18 mm when under this load. What is the stress and strain in the strut? Fill in the missing values in the following chart.
