the more i post on this the more confused i get

alpha zero; I know that its damping. it would be damping anywhere on Earth that's without a vacuum. but don't you think we should ignore the damping caused by air?... it will be pretty small. if there was a damper attached somewhere then you should have considered damping. this case is very...

waiittt.. we need to eliminate theta... i'll get back on tht after i take a nap

hi! I have seen a lot of questions on cantilever beams, but I am not familiar with this type. generally we're asked only to find out the maximum deflection at the tip, but you need the change in deflection with respect to time. so you have a case of SHM. suppose you bend a cantilever by...

I think you would still have 1450Nm at the 7inch pulley. i am saying this cause the axis of the shaft and the pulley are the same. I am a little confused though abt the calculation that u did with torque = force*distance. in a torque a couple acts and in a moment a force acts. the calculation...

for the record i think this question is incomplete. how can u have a gear train without knowing the type of gear train? and u need to atleast have one speed to get smthng good out of the problem to analyse (yes u can assume the speed but then where's the fun in tht). saying that i'll have a go...

1) take out the tire. 2) use a tachometer to measure the RPM at each speeds. u'll get N1, N2, N3, N4, N5, N6. 3) use the relation: RPM at first speed/RPM at second speed= gear ratio of 2 to 1. i.e. N1/N2=T2/T1. =1/7 4) the second gear ratio shd be N3/N2; the third shd be N4/N3 and so on. this...

so u have a ductile material in ur hands. i can tell u how to find 3 points on the curve. i don't knw wat RofA means but i guess it'll help u get a more accurate shape or more points for the curve. To draw the whole curve, u have the EL i don't what the unit in %age means but i guess u can...

maybe the tables used for finding enthalpy from temperature is different. are you sure about the credibility of the image? the guy has the units of temperature wrong ( mayb just a silly mistake).
