The picture below shows a typical machine, usually seen in an engineering workshop. Name the machine shown and describe its primary purpose.
Lathe machine: Used for shaping and machining metal or wood.
Drill press: Used for making holes in materials.

Grinder: Used for grinding and finishing surfaces.
Using Ohm's Law, calculate the voltage needed to run the circuit. Show your workings.
Voltage (V) = Current (I) x Resistance (R). Resistance is not given, so the answer cannot be fully determined from the information provided. If resistance is assumed or given elsewhere, V = 0.5 x R.
Voltage (V) = Resistance (R) / Current (I). Therefore, V = R / 0.5.
Voltage (V) = Current (I) + Resistance (R). Therefore, V = 0.5 + R.
Voltage (V) = Current (I) - Resistance (R). Therefore, V = 0.5 - R.

The difference between a destructive test and a non-destructive test is:
Destructive tests damage or destroy the material being tested, while non-destructive tests do not cause harm.
Destructive tests are always more expensive than non-destructive tests.
Non-destructive tests require more time to perform than destructive tests.
Destructive tests are only used for metals, while non-destructive tests are used for all materials.
Describe, using diagrams and notes, the testing process that has been carried out on the bike spoke for its tensile strength.
