Depends on what materials they are normally going to be using it on. Softer materials, such as wood products or soft metals, I'd suggest to get a drill with high rpm's. But if they are going to be using it to drill hard substances then I would direct them towards a drill with a higher torque, as this will help to avoid the drill freezing up or skipping on the materials.
They are both equally important in different scenarios. I don't know what you are talking about specifically, but on a drill RPMs are important when drilling through softer material to go faster, while torque is important on harder materials that can make the drill skip or freeze up otherwise.
It means the engine is developing 415 nm of torque at 1,600 revolutions per minute (rpm) or 306 Lb/Ft of torque at 1,600 RPMs.
Revolutions per minute The amount of revolutions the crankshaft in an internal combustion engine takes in 1 minute. Its the "speed" of the engine. The faster it rotates, generally speaking, the closer you'll get to its maximum torque and horsepower output. Trust me, it doesn't take one minute for the crankshaft to turn once. If it did, we would get like 500 miles to the gallon.
rpm is revolutions per minute ( revolutions of engine in neutral state ) pick up or torque is dependent on rpm .. 2200 is very revolutions .......... a simple 100 cc engine can create up to 8500 rpm depending upon the load on the engine ( weight of the vehicle)
MA = Revolutions of input shaft / Revolutions of output shaft. (Input torque * MA) * efficiency = Output torque Note 100% efficiency = 1.0
The torque in a car basically means the acceleration and power the engine gives when you floor it, the torque also depends on the RPM (Revolutions per minute) :which is how many times the pistons in your engine go up and down turn the wheels, so if your at 4000RPM and your giving of 500lb ft of torque that means your engine is very strong. Horse power is really how fast your car can go
orwhere P is the power in wattsτ is the torque in newton metresω is the angular velocity in radians per secondF is the force in newtonsv is the linear velocity in metres per secondDivision by a conversion constant may be required depending on the units of measure used.For imperial units,where Php is the power in horsepowerτlb·ft is the torque in pound-feetωRPM is the rotational velocity in revolutions per minuteFor metric units,where PkW is the power in kilowattsτN·m is the torque in newton metresωrpm is the rotational velocity in revolutions per minute
DynoRpms is revolutions per minute. How many times the engine turns a complete cycle. Torque is measured at the rear wheels(if were talking about a rear wheel drive car). Torque is the true power of an engine. If you have alot of horse power and low torque, the working power of the engine underload will be awful. The best way to measure and only true way is to Dyno the engine
Why is the right torque so important?
Boat engines are built to hold high rpms (revolutions per minute) for long periods of time. Vehicle engines are not built for high rps or most of the anyways. Vehicle engines also have more torque the marine engine.
Very important!
Downshifting is literally placing a vehicle's transmission in a lower gear, i.e. one with a greater number of revolutions of the driveshaft compared to the revolutions of the drive wheels. This is normally used to brake a vehicle using engine torque, to improve torque on steep grades, or to facilitate acceleration. Metaphorically, it is used to indicate a reduction in an economic activity, such as manufacturing output, by a single company or an entire industry.
