common tools - answer ✅✅useful for auto repair work: mig welder
different types of hammers - answer ✅✅- claw hammer: typical
household hammer you've most probably seen with claw on the other
end for picking out nails - most suitable for general carpentry
- ball-peen hammer: like a household hammer but with a ball thing
instead of a claw - most suitable for metalwork
- sledge hammer: a hammer that consists of a rod and a thick heavy
rectangular slab at the end - most suitable for breaking up concrete
- rubber mallet: like a sledge hammer but with a slightly more oval
shape rubber thing at the end of the rod - most suitable for
assembling a friction fit wooden frame
double pulleys - answer ✅✅There are two possible ways that two
pulleys can be used. Either one pulley can be attached to the weight
or neither of them can be.
example double pulley question - answer ✅✅pulley set up A has a
10kg load and two supporting ropes, B has a 10kg load and one
supporting rope

common tools - answer ✅✅useful for auto repair work: mig welder different types of hammers - answer ✅✅- claw hammer: typical household hammer you've most probably seen with claw on the other end for picking out nails - most suitable for general carpentry

  • ball-peen hammer: like a household hammer but with a ball thing instead of a claw - most suitable for metalwork
  • sledge hammer: a hammer that consists of a rod and a thick heavy rectangular slab at the end - most suitable for breaking up concrete
  • rubber mallet: like a sledge hammer but with a slightly more oval shape rubber thing at the end of the rod - most suitable for assembling a friction fit wooden frame double pulleys - answer ✅✅There are two possible ways that two pulleys can be used. Either one pulley can be attached to the weight or neither of them can be. example double pulley question - answer ✅✅pulley set up A has a 10kg load and two supporting ropes, B has a 10kg load and one supporting rope

A) A

B) B

C) Both require the same force Answer

  1. A - Weight A requires a force equal to 5 Kg whereas weight B requires a force equal to 10 Kg. Remember to divide the weight by the number of sections of rope supporting it to get the force needed to lift the weight. gears - answer ✅✅A gear is a toothed wheel or cylinder that meshes with another toothed component to transmit motion or to change speed or direction. Gears are attached to a rotating shaft turned by an external force, which is not usually illustrated in these types of question. Two gears may be connected by touching each other directly or by means of a chain or belt. gears connected by a chain or a belt - answer ✅✅If gears are connected by a chain or belt then they move in the same direction. meshed gears - answer ✅✅If the gears are touching (meshed) then adjacent gears move in opposite directions. In this example the first and third gear will turn in the same direction.

In B there are two sections of rope supporting the weight, so 10/2 = 5 Kg required to lift it. spring - answer ✅✅There are many different types of spring including, spiral coil, leaf springs and torsion springs. Springs are used in many applications including clocks, vehicle suspensions etc. In the type of questions that you will be asked in mechanical aptitude tests, you can assume that springs behave in a linear way. That is, doubling the force applied will stretch or compress the spring twice as much. spring compression example - answer ✅✅Example Spring Question

  1. A force of 5 Kg compresses the springs in series 10cm.What will be the total distance that the springs in parallel are compressed? aa0815.gif A) 10cms B) 2.5cms C) 5cms

D)7.5 cms Answer to Question

  1. C - The total force will be divided equally between the 2 springs in parallel. Since the force is divided in half, the distance moved will also be halved. The springs in series were compressed 10 cms, so the springs in parallel will be compressed 5 cms. springs - answer ✅✅A spring is piece of wire or metal that can be extended or compressed by an external force but which then returns to its original length when that force is no longer applied. Springs in Series & Parallel - answer ✅✅If more than one spring is used then they can be arranged in one of two ways, either in series or in parallel. When springs are arranged in series, each spring is subjected to the force applied. When the springs are arranged in parallel the force is divided equally between the springs. Series = springs next to each other Parallel = springs stacked up like electric circuits you can think of springs in series like addition of the force

A) 100kg B) 150kg C) 50kg D) 60kg Answer

  1. C - The weight is 300 Kg and there are 6 sections of rope supporting it. Divide 300 by 6 to get 50 Kg. In all cases, just divide the weight by the number of sections of rope supporting it to get the force needed to lift the weight.
