Look at flexions at the point of supprt:\n1 is the support solid so its flexure can be ignored\n2 is the steel rod held by a grub screw. If it extends any distance to lock the rod then some rotation will occur due to it bending\n3 if held in a chuck check slippage.\n\nIn motor cars torque transmission is usually accomplished using splined shafts, but for small oscillations the backlish in these will be large.

22-d, 28-b, 30-c\n\nA baseball has rotation and translational motion.  Torque is a measurement of the ability to produce angular acceleration, while force is related to the translational acceleration (hence 28-d is false)  28-a and 28-c are equivalent, which should have been a clue that 28-b is the right answer.

15a) Ahh, lengths, areas, and volumes. Lengths are proportional to each other, areas are proportionatl to the square of the length, and volumes are proportional to the cube of the length.\n\na) The ratio of the area of the windscreen is ⅜^2\nb) The ratio of the capacities of their boots is ⅜^3\nc) The ratio of the widths is ⅜\nd) I suppose the model car has four wheels, just the original. It's a model, after all.\n\n15b) we are looking for a rectangle with area equal to 16. Let the width be w. Then the length is w + 6.\n\n16 = w(w + 6)\nw^2 + 6w -16 = 0\n(w + 8)(w - 2) = 0\n\nw = 2, and the length is 8. The area is 16.

Assume s=275, v=43, r=0.21 & t is time from start to stop; then v=a*t & s=a*t^2/2, ‘a’ being deceleration. Therefore t=v/a, s=a*(v/a)^2/2; thus 2*s*a=v^2 or a=v^2/(2*s).\nAngular deceleration w’=a/r.\nNow I=0.175, so frictional torque T=I*w’. plug numbers in.

Check this:\nhttp://www.engineershandbook.com/Tables/torque.htm\nAlso, the head of the bolt will have small lines on it; the higher the number of lines, the stronger the bolt.  I'm not sure what the exact numbers are.  "Machinery's Handbook" and other references can tell you.  It's probably on the Internet, too.

a 383 is a stroked 350....a stroked engine makes alot more torque there for needing to change gears less you can pretty much run the same gear around the whole track

Variables: 150 rev/min  2.2h = 140 min \n(a) Difference in velocity (150 to 0) over difference in time (0 minutes to 140)\ndelta v / delta t   (150-0)/(0-140) = -1.0714 rev/min/min\nAcceleration is negative since it is slowing down.\n(b) during the slowdown? one less than the answer to (c)?\n(c) (v not times delta t) / acceleration absolute value  (150*140)/|-1.0741|  =  19553.07 revs\n(d) and (e) email if you really want, but this stuff should give you a start.

The four bolt is stronger. As for re-conditioned vs crate, I'd go with the re-conditioned engine. The crate motor is manufactured on an assembly line and will be a new stock engine and will have some break-in needed before you start to hammer with it, as we know you will. A reconditioned motor from a muscle car shop will be hand assembled by a trained and experienced technician. It will probably be balanced and have all the clearances right. In addition, it may have things like chamfered oil holes on the crank as well as being shot peened to remove any burrs. A reconditioned engine like this will serve as a good foundation for any other mods you wish to do.

The second set of numbers represents the length of the brass in millimeters. A 7x ("x" reads "by") 57 means that the case, just like an 8x57 is just that, 57mm long. While strange by US standards, try explaining the meaning of 7-08Rem or 7-30Waters to those on the east side of the pond. I also have and love my 7x57. Very mild, but shoots good and flat out a lot further than I can see. My neighbor has a Mauser in 7x64. Wonderful round! Finding ammo is a bit problematic though. He forms his brass from .270Win Seems to work for him.
