ASVAB practice test 1 (100 out of 100) Questions
and Answer Elaborations (GRADED A)
An induction clutch works by magnetism If a first class lever with a resistance arm measuring 2 feet and an effort arm measuring 8 feet are being used, what's the mechanical advantage? Length of Effort Arm ÷ Length of Resistance Arm. MA = 8 ÷ 2 = 4 The force produced when a boxer's hand hits a heavy bag and "bounces" off it is called recoil If Gear 1 has 25 teeth and Gear 2 has 15 teeth, how many revolutions does Gear 2 make for every 10 revolutions Gear 1 makes? r = DR/d, r=16. Springs used in machines are usually made of steel A clutch is a type of coupling
A single block-and-fall is called a runner The mechanical advantage of the block-and-tackle arrangement shown below is
- Because this block-and-tackle arrangement merely changes the direction of the pull, it has a mechanical advantage of only 2. If a house key, a wooden spoon, a plastic hanger, and a wool jacket are all the same temperature, which one feels the coldest? The key will feel coldest because metal is a better conductor than the other materials A way to determine the amount of power being used is? The formula for determining power is Power = Work ÷ Time. A wood tool, a silver tool, and a steel tool are placed in boiling water for cleaning. Which tool gets the hottest? Silver is the best conductor, so it becomes hottest If an alternator overcharges the battery, a likely explanation is The voltage regulator isn't working properly A primary advantage of the electronic ignition system over conventional ignition systems is The electronic ignition system provides a higher voltage
Nail sets are used to set nails below the surface of the wood A ripsaw cuts with the grain of the wood A bucking bar is used to drive rivets Washers that have teeth all around the circumference to prevent them from slipping are called shakeproof washers Ohm's law states Voltage = Current × Resistance. V=IR An electromagnetic-induction device usually has which of the following materials in its core iron How many diodes should you expect to find in a bridge rectifier? A bridge rectifier is also known as a full wave rectifier, usually containing 4 diodes Another name for cycles per second is:
hertz When current flows through a wire, the following influences are present voltage, ohms, amperes Millihenries are related to inductors Radar can operate at frequencies as high as 100,000 MHz Radio waves travel at the speed of light Changing alternating current to direct current is called AC to DC is a process called rectification Insulated fittings can be used to splice wires, thus eliminating the need for soldering the wires together How many wires do serial cables used on computers have? 9
proficient adept plenary full goad incite headlong recklessly flagrant glaring opposite of stimulate arrest legacy bequest
unconscionable excessive laudable commendable burnished polished oblique obscure superfluous unnecessary opposite of hypocrisy honesty garrison fort
persists contravene obstruct chasm hole susceptible gullible A series of cell divisions that results in the formation of an embryo is called mitosis The process by which energy is provided at the cellular level is called metabolism Light waves travel at a rate of about 186,000 mps The largest moon in the solar system is Ganymede
Which inorganic substance is present in the greatest quantity inside animal cells? water Cell protoplasm is made up mostly of: water The chamber of the heart that pumps blood to the lungs is called the right ventricle The atomic number of an atom is determined by
of protons
How many planets in the solar system have rings? 4 Not counting the sun, the closest star to the Earth is Proxima Centauri
