TYPES OF FORCES THAT ACT ON A STRUCTURE
Activity: Copy in your notebook this structures. Which of these structures is stable and which is non-stable?. What can you do to make them rigid?.
|Label the sketch to indicate a member that is in tension and a member that is in compression.||This saw blade is in tension/ compression/shear. Circle the correct answer.|
|The rope marked X is in shear/ compression/ tension. Circle the correct answer.||4. Name the force acting on the material shown.|
|Name the force acting on the fabric.||This rope is in tension/ compression/ torsion. Circle the correct answer.|
|The pin shown is in tension/ compression/ shear. Circle the correct answer.||Identify the forces shown in the sketch.|
9. When bicycle brakes are pulled, the force between the brake
blocks and the wheel is a bending force/friction force/shear
force. Circle correct the answer.
10. The beam shown is bending under a load. Identify the parts X, Y or Z of the beam which are (a) in compression (b) in tension (c) neither in tension nor compression.
Sketch: A simple, rough drawing, done rapidly and without much detail.
