aha, this old chestnut.. the one that most people seem to struggle with.
in Surfer dood terms.. heres what happens and what it means.. as Davina would say.. then YOU decide...
I will use my beer bottle analogy lol..
let us consider torque to start with..
there is a guy, called Fred, who applies for a job at the local ale house.. he refills the bottle shelves when empty.
Now... how many bottles can Fred lift in one go ??. - basically depends on how strong he is yep ?..
So, - Fred, cos he works out.. can lift 48 bottles in one go.
his maximum lifting capacity we can call his torque.
this is all well and good.. but to know if Fred is the right man for the job, we need to know how much work he can do... this work, we will call BHP (Bottles he processes lol)
All Fred has shown us so far is that he can lift 2 crates (48 bottles) in one go.
but, we want him to move those bottles from the celler to the bar.
we time him, and it takes him 30 seconds to carry the 48 bottles to the bar.. so, we can work out roughly how many bottles per hour he can move yep ?.
If we try to increase the number of bottles he carries, he may stagger and slow down, maybe taking 35 seconds to get to the bar.
His work output (BHP) is therefore based on the number of bottles he can carry in one go.. and the time it takes to do the trip to the bar.
Bill comes along to the interview.. this time, Bill is not as well built as Fred.. he can only physically lift 1 crate at a time (24 bottles).. his torque is lower.. but it is meaningless unless we know how fast he can get to the bar.. because Bill is built like a racing snake.. he whips the 1 crate to the bar in 14 seconds..
His work output is his torque (Amount he can lift) times the number of trips he can accomplish, in say an hour.. times the number of bottles.
if the return to celler time is the same for both guys.. it is actually Bill who moves more bottles and hence does more work in a given time period.
Now Jim comes along.. Jim is built like a brick outhouse... he can lift 4 crates no problemo.. he jogs to the bar in 17 seconds.... who does more work now ??
The wieght of the bottles is the key here, not the physical size of them.. the end result is a weight moved over time..
the meaning of all this.. ???
there is no difinitive answer for which is better .. it is a matter of knowing the weight to move and the time it takes..
now find something to fit the profile.
