In a hydraulic lift, the radii of the pistons are 2.55 cm and 9.8 cm. A car weighing W 11.0 kN is to be lifted by the force of the large piston.(a) What force Fa must be applied to the small piston?(b) When the small piston is pushed in by 11.6 cm, how far is the car lifted?(c) Find the mechanical advantage of the lift, which is the ratio W / Fa.
2-5 bhp can be expected with the addition of a cold air intake on a 4 cyl. straight from my motor builder/dyno guy's mouth. he uses a newer top notch dyno and has tested these things claims out on a few different occasions
It will be very little HP gain and it will make your car a little bit louder. Bolt-on parts like a cold air intake will not add a significant amount of horsepower to a 4 banger engine. And yes, there is a downside to adding one. Cold air intakes usually have their gains in the mid-RPM range. They actually WORSEN your torque in the low RPM range (that means your acceleration off the line suffers).
if its a gt your looking at 2-5bhp its in the mid range. if its a gt-s your looking at 3-8bhp in the mid range but also more at the top end. do not put 3inch piping on it. the intake really adds more power because the pipe is bigger while the stock air box is more restrictive. if you go to big of piping the car will bog. also a known risk with cold air intakes is hydrolock in which your intake sucks up water into the engine (happens when you submerge it in water by splashing through a big puddle) and locks up the engine. Short ram intakes with a heat shield are a better option.
tension section X tension I consistently artwork in PSI and Lbs, and Inches (i'm outdated college and nver use metric, so I consistently convert them over) you could convert the burden to lbs and section to inches and regulate the formula to tension tension divided via section From what you have right here, I form of anticipate that the 36cm is 36cm squared and is the element of the cylinders piston? (length does not be counted) you ought to make sparkling that.
(a) Fa 11.0kN * (2.55 / 9.8)^2 0.745kN 745 N (b) lift distance 11.6cm * (2.55 / 9.8)^2 0.785 cm 7.85 mm (c) W / Fa 11000 / 745 14.8
