Work and simple machines answer sheet?
The fulcrum is the part of a lever that does not move. The effort is the name of the force applied to a lever. The load is the weight of the object being lifted by a lever.
What kind of simple machine is a weighing scale?
A weighing scale is a type of lever, which is a simple machine. The torque applied to one end of the lever determines the amount of weight on the other end.
how much weight does it take on a lever to lift 500 lbs?
The weight needed on a lever to lift 500 lbs depends on the lever's fulcrum placement and length of each lever arm. In a simple lever system, if the fulcrum is placed at 1/4 of the distance from the load to the effort, then the weight needed would be 125 lbs. However, this can vary based on the specific design of the lever system.
How can you find an object's weight from a lever?
To find an object's weight using a lever, you can use the principle of torque. By measuring the lengths of the lever arms on either side of the fulcrum, along with the distance from the object to the fulcrum, you can calculate the weight of the object. This is typically done using the formula: weight = force x distance.
Is an airplane a simple machine?
An airplane is not a simple machine. A lever is a simple machine. A wheel is a simple machine. Any machine that can be described by a mathematical formula is a simple machine.
What is a lever balance?
A lever balance is a simple machine used to measure weights by comparing an unknown weight to a known weight. It consists of a bar that pivots on a fulcrum, with the two sides of the bar holding the weights. When the lever is balanced, the weights on each side are equal.
What type of simple machine are handlebars?
Handlebars are a lever because you put your weight upon them to balance.
What simple machine is a crutches?
Crutches are a type of lever, which is a simple machine. The user's body weight acts as the effort force applied to one end of the lever, while the ground acts as the fulcrum. This allows the user to reduce the force needed to support their weight while walking.
How much weight is required to balance the lever?
The weight needed to balance the lever depends on the distance of the weight from the fulcrum and the weight on the other side of the lever.
What a lever does?
A lever is a simple machine that uses variable distance to multiply force, or to redirect existing forces. With a lever, the force exerted by gravity on a weight can be used to lift another weight. By varying the distance between a lever's ends and its fulcrum, a heavy object can be lifted a short distance by a smaller force moving a longer distance.
