 force equals... mass times acceleration a force is a .. push or pull that causes a change in shape or motion mass is the total amount of what..in an object its meassuerd in grams or lb.mass matter weight is the measurement of.. gravity times mass this is a force like quanity in rotational mechanical system meassuerd in n.m si or in lb.ft torque whean forces act in the same dirrection the .....is the sum of both forces net force what are the prime movers in fluid,electrical, and thermal systems preesure differece,voltage, and tempeture difference. what is found by dividing mass by volume. density what is a hydrometer used to messure.. density or specific gravity in liquids what is meassuerd by dividing a unit of force by a unit of area. includes p.s.i pressure manometeres are used to meassure.. pressure differences the two types of fluid are.. hydraulic (using liquids) (and pneumatic (using gas) gasses are..... liquids are not.. compressible what increases with depth in fluid but is independent in volume pressure absolute pressure is the meassure prressure diffrences what is weight density.. the ratio of an objects weight to its volume the weight density of water i 62.4 what comes in two forms and how.. voltage..(a.c) (d.c) (d.c)=comes from batteries and (a.c)=comes from is alternating current of electrons that move back and fourth voltmeters. measure voltage difference multimeters messures voltage amprees and resistance (in ohms) the positive pole(tip) oe electrode in a battery is.... whats the negative pole.. the anode..the cathode what do electrical circuits contain.. a source(battery),conducters(wires for transmison of electricity),and a load (light bulb) also may contain a switch .......acts as a prime mover in thermal systems because heat allways moves from warmer regions to cooler regions tempeture difference a form of energy charecterized by the vibrating movement of atoms and molecules. heat what is tempeture. its the mesure of average energy of motion of molecules in a substance what uses three wiers of two different meatels to measure temoeture.. thermocouples what does work =.... force(or force like quanitys) times the distances (or a displacment like quanity) what is the work going into the system... input work (done by a human or a motor) what is work done by the system(computer) output work .......is divided by output work divided by input work multiplied by 100 (efficancy cannot exceed 100%) efficiency what are used to measure input and output force... spring scales in rotational mechanical system .....is equal to torque multiplied by the angel throught wich arm moves. work what is the basic english unit of work.. foot/pound in rotational mechanical system .....is equal to torque multiplied by the angel throught wich arm moves. work the basic SI unit of work is the ..... newton/meter (1n.m=1joule) what is the basic english unit of work.. foot/pound linear mechanicak work is preformed whean what.... a mass is moved in a straight line the basic SI unit of work is the ..... newton/meter (1n.m=1joule) angular mechanical work is done whean... a mass is moved around an axis or rotation. linear mechanicak work is preformed whean what.... a mass is moved in a straight line mechanical work causes an object to what... start moving stop moving or change direction what is fluid work equal too.... its equal to the presure difference times the volume moved (w=dpTIMESv) angular mechanical work is done whean... a mass is moved around an axis or rotation. whean givin the height a fluid is raised you must also know the ...........of the fluid in order to calculate the fluid work weight density in a hydraulic brake system what happens to the fluid the fluid is reused mechanical work causes an object to what... start moving stop moving or change direction is linear and angular.. a fluid work.. no thears no such thing what is fluid work equal too.... its equal to the presure difference times the volume moved (w=dpTIMESv) whean givin the height a fluid is raised you must also know the ...........of the fluid in order to calculate the fluid work weight density in a hydraulic brake system what happens to the fluid the fluid is reused is linear and angular.. a fluid work.. no thears no such thing
