2.7. G

Try these first

1. 1.

   Define 'Force'.

   Hint

   Think about what you exert when pushing a door open.

2. 2.

   What is equilibrium?

   Hint

   Recall the example of a book on a table.

3. 3.

   What term describes the balancing of forces?

   • Equilibrium
   • Force
   • Moment

   Hint

   Think of a stationary object.

4. 4.

   True or False: A moment can be created without applying a force.

   • True
   • False

   Hint

   Remember the definition of a moment.

5. 5.

   A force of 15 N is applied at a distance of 5 meters from a pivot. Calculate the moment about the pivot.

   Hint

   Use the formula for moment: Moment = Force × Distance.

6. 6.

   In a cantilever beam, if the distributed load is 20 N/m over a length of 4 meters, calculate the total load on the beam.

   Hint

   Consider how much weight is spread along the beam's length.
