Which term describes the upward push of fluid on an object in the fluid?
Buoyant force
Which term describes the upward push of a fluid on an object in the fluid?
the 'buoyant' force
What happens in density of this gases as altitude increases?
Density decreases as altitude increases ... because there's less atmosphere above it to push down.
What happens when you pull or push a spring?
mmm
Do pumps push or pull?
Both. On the down stroke of a piston pump, the chamber is evacuated, pulling the material in. On the up stroke, it pushes the material out.Similarly, in a turbine pump, low pressure on the intake side pulls and high pressure on the output side pushes.The exception is the mechanism used in bicycle pumps and old-fashioned water pumps (and toilet plungers). In these, half the cycle is wasted as the plunger contracts and goes through the fluid. On the "power stroke", the plunger expands and pushes the fluid out (or in, in the case of the toilet bowl plunger).
If you pushed down on a piston in a fluid what happens?
the piston would push air down and fluid up.
What is use to push caliper piston in caliper?
Hydraulic force, transmitted by the brake fluid.
How hydraulics machine work as a magnifier?
A piston with a small surface area, is used to push fluid through a pipe, to a piston with a large surface area.The force used to push the small piston, will be divided into the larger surface area of the second piston.The larger piston will move a smaller amount, but will have more force, proportional to the difference in sizes.
How do you push the piston completely in the caliper?
Take the cap off the the top of the master cylinder where you put your break fluid in and push back. Watch out because the fluid will go all over the place. So make sure you have a rag ready.
What does a wheel cylinder do?
Operates the brakes when the pedal is pressed. The pedal pushes the master cylinder, this pushes brake fluid down the brake lines, the fluid pushes the piston(s) in the wheel cylinder, the pistons push the pads or shoes onto the drum or rotor which is attached to the wheel.
How do you push the caliper piston back after taking off old brake pads on a 1994 ford explorer?
use a large c clamp and push the piston back in, just be sure to not over fill you master brake cylinder because you will be pushing more fluid into it.
What causes a piston in an engine to move?
the explosions which are caused by the throttle being pushed down and the harder you push down the throttle the bigger the explosion ANSWER for single piston , power stroke force the piston to bdc . but during any other stroke , the inertia of the spinning crankshaft force the piston to tdc n bdc
How do you back up the piston in the caliper on the rear brakes of a 2002 X-type?
AnswerSometimes if piston wont push back in try twisting it back in. Its on a 'staircase' pawl. Twist. push, twist, push etc.Use a 12mm (about 1/2inch) hex key to rotate the piston at center hole. no need to push, just rotate. Before rotation don't forget to let the handbake off, and brake fluid reservoir open.Check the piston gaskets and replace if needed (Ford Mondeo MK3 compatible), the set for the Ford Mondeo is about 11$ per caliper.
You cant push the piston on your rear brakes back in on my 02 Volvo s40?
Sounds like a siezed piston. This occurs typically from two causes. Either the piston is not aligned perfectly with the cylinder bore or there is corrosion on the cylinder walls behind the piston preventing it from going into the bore. Brake fluid is hydoscopic, meaning it attracts & absorbs water. If the fluid is not changed at the recommended intervals, any moisture in the fluid will cause corrosion in the brake lines, cylinders, etc. The solution is to remove and rebuild or replace the caliper. A flush of the brake fluid would also be prudent. The rear brakes on your '02 s40 are slightly different from the front. On the front, you can press the piston in. On the rear, the piston needs to be screwed in. Notice the slot going across the head of the piston? There is a special tool that looks like a small block and sits on top of piston and a small piece sets in the slot as the block sits on the piston. Turn clockwise to press in. You can use pliers of some sort but need to be careful because you can rip the rubber. You need to turn the piston in clockwise direction to push in the piston
What is piston in bike?
A piston is pretty much the same wherever you find it. It's a cylindrical lump of metal that fits snugly inside a length a pipe, a cylinder. By creating a pressure on one side of the piston you can get it to move, to transfer force. Pistons are found in combustion engines, where the gasses from the burning fuel push the piston(s) down an power the engine. They're also found in braking systems. The brake pedal push down on one piston, creating pressure. The pressure moves through a pipe into the brake caliper, where anothe piston cause a brake pad to move and push against a moving surface. Pistons are also found in shocks, where the movement of the piston against an enclosed gas/liquid slows the movement of the vehicle down in a controlled manner.
How do you change the pads on the front breaks of a 02 Pontiac Montana?
Remove the wheel and use a 15mm socket to remove the brake caliper bolts. Set the caliper aside and replace the pads. You will need a C-Clamp to push the caliper piston back in to accommodate the new pads. You will need to remove some of the brake fluid from the master cylinder before you push the caliper piston in because the fluid level will rise. If you do not remove any fluid it will over flow and make a mess. BRAKE FLUID EATS PAINT. Reassemble and pump the brakes. Add fluid if needed.
What happens to the brake shoe and drum when the pedal is pressed?
The brake shoes are inside the drum, which is turning along with your wheel. When you press the pedal, it pushes fluid through the brake line, and that fluid forces the shoes outward and they push on the inside of the drum, which slows it down, and thus slows down your car.
