What is the lever system?
Next to the wedge, the lever is the simplest tool used by mankind. In its basic form, a single lever is stiff straight rod that rests on a pivot point called a fulcrum. The length of the rod is L, its length from one end of the rod to the pivot point is l; so the length from the pivot point to the opposite end is L - l. We can show that F = f (l/(L - l)) increases the input force f to F > f when (l/(L - l)) > 1.0. The ratio (l/(L - l)) is called the mechanical advantage of the lever. EX: If L = 10 and l = 9, then 9/(10 - 9) = 9 is the mechanical advantage. So that F = 9f would be the result.
What are torques?
Torque is a force that is applied to a lever. (Imagine a rachet. As you tighten a bolt, you push on the handle, which is essentially a lever. This lever exerts torque on the bolt, causing it to spin) Torque is defined as T = r cross F, or just R X F. Basically, if you multiply the force by the distance of the force from the central point on the object you are trying to rotate, you have torque.
Is a crowbar a lever or a fulcrum?
A crowbar is a Class 1 lever (fulcrum or pivot in the middle) The trick to remembering which type is which is: FRE 123. If F the fulcrum is in the middle it's Class 1, if the Resistance (or load is in the middle (a wheelbarrow) it's Class 2 and if the Effort is in the middle (tweezers) it's Class 3.It's a class 1 lever because the curve part of the crowbar (the fulcrum) is in between the effort, at the end of the crowbar where your hands are, and the load side, the short side that pry's the thing open.
What is the function of the fulcrum on a lever?
The fulcrum on a lever is the pivot point that allows the lever to rotate. It acts as a point of support around which the lever can move to either amplify force or distance. It plays a crucial role in determining the mechanical advantage of the lever system.
What is a compliment starting with letter F?
Fantastic or Fashionable can be a compliment starting with letter F.
Look at the metric ruler pictured Assuming that 0 is visible on the ruler and is also the starting point what is the distance to point F?
answr the question39mm beats the answer above dont know if its right3.0CM ;)
What is the boiling point of water in F and what is the freezing point of water in F?
The boiling point of water in Fahrenheit is 212°F. The freezing point of water in Fahrenheit is 32°F.
Are fahrenheit units the same size as kelvin units and why?
No, Fahrenheit units are not the same size as Kelvin units. This is because the Fahrenheit scale is based on a different reference point (32°F for freezing point of water and 212°F for boiling point of water) compared to the Kelvin scale, which uses absolute zero as its starting point (0K).
Boiling point and melting point of copper?
The boiling point of copper is 2567°C (4653°F), while the melting point is 1084.62°C (1984.32°F).
What is the melting and boiling point of chlorine in Fahrenheit?
The melting point of chlorine is -150.7°F and the boiling point is -29.27°F in Fahrenheit.
How do you change a gear shift lever on a 1997 Ford F-350 4x4?
If it is a manual trans.take the screws out holding the shift lever boot on. Slide the boot up the gearshift. there will be a bolt holding the lever on, take that out and pull on the lever. you may have to get a little rough with the lever to get it to come off once the bolt is out.
What are examples f a lever?
a teeter-totter (see-saw) a light or elecrticity swtch
