1) How do you check a chain for elongation? Report

Apply a load, measure chain and use 5% max formula to check extension

Apply a load, measure chain and use 2% max formula to check extension

Hang the chain under its own weight, measure chain and use 2% max formula to check extension

2) How do you store a chain? Report

Oiled and coiled in greaseproof paper

Lay uncoiled and flat in greaseproof paper

Hanged so they do not kink

3) Epicyclic gears are used on Report

shafts rotating on axis 90 degrees from each other

shafts rotating on the same axis

shafts rotating on offset axis

4) What is the purpose of the guard, where a control chain goes around a sprocket? Report

Stops the chain coming off if it goes slack

Protects personnel when carrying out maintenance

Prevents entry of foreign bodies

5) Worm drives operate in shafts which are Report

90 degrees to each other and in a differing plane

90 degrees to each other and in the same plane

parallel to each other and in the same plane

6) The pattern of a gear is Report

The pattern of a gear is the

the mark it leaves on a mating gear

the path they take when the gear is rotating

7) How is the change in direction of a control chain, in two planes, achieved? Report

By using a pulley

By using spring clips

By using bi-planer blocks

8) How is a non-reversible chain different from a normal chain? Report

By use of a chain guard

Every second outer plate is extended in one direction

Different end fittings

15) A feather key locates a gear on a shaft and permits Report

positive drive and axial movement

positive drive with the gear firmly locked

a positive and strong drive for transmissions

16) A worm drive creates Report

a drive in 2 planes and transmits both directions

a drive in 1 plane but transmits both directions

a drive in 2 planes but transmits 1 direction only

17) The teeth of a gear would normally be Report

nitrided

tempered

case hardened

18) If a chain is removed for routine maintenance Report

it must be proof checked to full load

it must be proof checked to ? max load

it does not have to be proof checked

19) On gear teeth, the wear pattern should be Report

even from top to bottom

the top edge most worn

the middle of the tooth most worn

20) On bevel gear teeth, the wear pattern should be Report

at the centre of the tooth

greatest at the heel, least at the toe

greatest at the toe, tapering off to the heel
