In a single fixed pulley, you pull (apply force) straight down (pull down). In a first-class lever you push up (apply force) , but not push.

Single Pulley
Fixed pulleys are similar to, and are considered by many to be, first class levers. In a first class lever, the fulcrum of the lever is placed between the load (resistance) and force (effort). In a fixed pulley, this is essentially the same. Picture a piece of rope hanging from a ceiling from one end, and with you holding the other end. A weight on a pulley is placed in the middle. Now, if you pull up on the rope, the weight rises, just like with a first class lever. Since the load is between the fulcrum (the pulley) and the effort (you pulling up), the fixed pulley acts like a first class lever.
First Class: On average about 1,000 pounds but since there was no fixed rates a first class ticket could cost much more or a little less. Second Class: On average about 450 pounds but again since there was no fixed rates prices could be very different. Third Class: On average costs about 30 pounds but because of no fixed rates it could be a little more or a little less. These are just averages a ticket could cost much more of much less.
class limits is where the numbers are fall.from begining to end.a class interval is when a fixed no. are decided for eg.0-5,5-10,10-15,15-20 are inclusive class intervals.
There are three main types of chainset bikes available in the market: single-speed, geared, and fixed-gear. Single-speed bikes have one gear ratio, geared bikes have multiple gears for different terrains, and fixed-gear bikes have a single gear with no freewheel mechanism.

Nothing, really. Most mail is assumed to be sent First class, which is the standard or regular mail. If you are sending merchandise, you can reduce the cost, but it will not get certain priority handling. There are many different rates that can be used in bulk mailing, but First Class is usually going to be your best bet.

The term acid does not refer to any single substance but a class of chemical compounds.
single fixed pulley changes the direction of the applied force, you pull down, the object goes up.
