SOLUTION QUESTIONS AND ANSWERS
VERIFIED
◉ AC Circuit. Answer: Electrical circuit where current can flow in
both directions, constantly reversing
◉ DC Circuit. Answer: Electrical current moves through the circuit in
only one direction
◉ Elevator safety features. Answer: - Strict regulation of equipment
- Rigorous engineering
- Safety devices
◉ Terminal device. Answer: Electric switch that terminates power
before the car reaches upper or lower limits of the hoistway
◉ Buffers. Answer: Large springs or hydraulic cylinders and pistons
at bottom of elevator pit that act as shock absorbers if terminal
switch fails, can NOT stop a car in free fall
◉ Speed-reducing switch. Answer: Aka speed governor, slows drive
motor when car exceeds safe speed
, ◉ Overspeed switch. Answer: Connected to speed governor, actives
if speed-reducing switch unable to slow car sufficiently
◉ Car Safeties. Answer: Tapered pairs of steel jaws that wedge
against the guide rails and bring the elevator to a stop, designed to
stop a free-falling car
◉ Elevator pit. Answer: Depression at the base of an elevator
hoistway that contains equipment and maintenance access
◉ 3 common types of hoistways. Answer: Single, Multiple, Blind
◉ Blind hoistway. Answer: Two or more shafts that only go to a
certain level, serve only upper levels of taller buildings ex. 1-20 and
21-40 floor
◉ Shear Wall. Answer: Wall panels that are braced against lateral
loads, can be load and non-load bearing
◉ Mushrooming. Answer: Tendency of heat and products of
combustion to rise until they encounter a horizontal obstruction and
spread laterally until they cannot and bank downwards
