how long can your d.ick erect?
-
for me, i can hold my c.ock standing continuouslly at 20 minutes when i was young
-
lol, I tot u meant the length the dick can go up to
-
Depends on temperature, cos if heat is gained (outside temperature hotter), the internal energy (U) increases (take it as closed system), therefore Energy of the system is = mass x U since the boundary can be taken as fixed and unchanged, therefore we do not take into account boundary work Wb.. since energy is needed to maintain erection, the more energy u have, the longer u can sustain.
come, jit ba hoon hor wa -
sth lidat la... but i tink i got a better explanation for this... by the 1st law of thermodynamics, internal energy, U = q + w, where q = heat gain/loss and w = work done.. so work done here is brought abt by how much work u do on ur dick...in laymen's term it means how hard u rub ur dick... in order to gain higher internal energy which will mean longer dick standing, u need to put ur dick into boiling water.. so there will be a great heat gain.. den u muz do a lot of work on ur dick too.. hence great work done.. As q and w go infinite, U goes infinite too.. As U goes infinite, time ur cock stands goes infinite..Originally posted by chunyong:Depends on temperature, cos if heat is gained (outside temperature hotter), the internal energy (U) increases (take it as closed system), therefore Energy of the system is = mass x U since the boundary can be taken as fixed and unchanged, therefore we do not take into account boundary work Wb.. since energy is needed to maintain erection, the more energy u have, the longer u can sustain.

you need to take into account the heat lost too
you need to take away the ((% area of dick exposed to air) x (rate of cooling caused by air) +(100%-% area of dick exposed to air) x (rate of cooling caused by hand in motion))
where rate of cooling caused by air = (temparature of dick - temparatue of air)/(1/(resistance of dick+ resistance of air))
rate of cooling of hand in motion = (temparature of dick - temparature of hand)
/(1/(resistance of dick+ resistance of hand))
since there is heat loss , the dick can't stand forever and is bounded by time
provided heat lost > heat gained -
Wah liao....Physics is needed to explain erection

suppose we have a vertical cylindrical pump used to move a Newtonian fluid to a height of x cm above where it is stored. when a force is applied parallel to the shaft for a certain number of times the fluid will move the length of the tube and be discharged at the top of the pump.Originally posted by I_am_PeTe_Parker:
Wah liao....Physics is needed to explain erection
the pump is 15 cm long and has a 5cm diameter. the fluid is being pumped from 2 spherical containment vessels at the base of the pump and has a capacity of 300 ml each.
there is a stiffening constant of the shaft k, based on calculations of the internal mechanics of the pump, so that complex calculations can be avoided. the rate of change of the length of the pump is kx.
deli 1971 uses jis pump to cause all of the fluid in the containment vessels to be discharged in exactly 20 minutes. Assuming a 70% load delivery to load effort ratio. and given that 6L of the unknown substance can be compressed to 3L wotj a pressure of 50 MPa in 2 minutes. how much work does he do on the shaft? -

hey!! wake up and do physics!!Originally posted by beavan:-.-" -

u forget as your cock stand tends to infinity, ur time indoors also tends to infinityOriginally posted by red_tide24:sth lidat la... but i tink i got a better explanation for this... by the 1st law of thermodynamics, internal energy, U = q + w, where q = heat gain/loss and w = work done.. so work done here is brought abt by how much work u do on ur dick...in laymen's term it means how hard u rub ur dick... in order to gain higher internal energy which will mean longer dick standing, u need to put ur dick into boiling water.. so there will be a great heat gain.. den u muz do a lot of work on ur dick too.. hence great work done..

u guys r so funny !

sorry hor....it is not physic hor......if physic can explain erection, then what can u explain about the gravity-defying effect?
for me, my erection can last for as long as i am stimulated....for example, in a case of me watching porn VCD, visual stimuli causes adrenalin to be released and heartbeat increases.......increased and rapid blood flow also follows.....
continuous visual stimuli resulted in continuous pumping of blood into the blood streams and arteries of our penis.....thereby sustaining the erection for as long as the porn movie can last....
don't agree? SAY!!!!

i should have studied harder, lol
anyway the 300ml is as big as coke can -
u want long, u double or triple tie a rubber band around the base, u want a few days also no problem.
