it is d ratio of the load to the effort applied to move the load if mechanical advantage>1(ie L/E >1), the machine acts as a force multiplier otherwise as a machine to gain speed mechanical advantage is abbreviated as M.A.
Simple machines increase mechanical advantage.
Simple machines, such as a lever, inclined plane, or wheel and axle, give you a mechanical advantage.You calculate the mechanical advantage of a simple machine by dividing the output force by the input force.
When a machine has a certain mechanical advantage, it means that it can multiply the input force applied to it. Mechanical advantage is calculated as the output force divided by the input force required to lift a load. Machines with a mechanical advantage greater than 1 make it easier to lift heavy objects.
you have to multiply the individual mechanical advantages of all the simple machines that make up the compound machine.
you have to multiply the individual mechanical advantages of all the simple machines that make up the compound machine.
you have to multiply the individual mechanical advantages of all the simple machines that make up the compound machine.
Mechanical advantage for the six simple machines are: Lever: Mechanical Advantage = Length of Effort Arm / Length of Load Arm Pulley: Mechanical Advantage = Number of ropes supporting the load Wheel and Axle: Mechanical Advantage = Radius of Wheel / Radius of Axle Inclined Plane: Mechanical Advantage = Length of Incline / Height of Incline Wedge: Mechanical Advantage = Length of Sloping Side / Thickness of Wedge Screw: Mechanical Advantage = Circumference of the screw / Pitch of the screw
The actual mechanical advantage of a machine is usually less than its ideal mechanical advantage due to factors like friction, energy loss, and imperfections within the machine. These losses reduce the efficiency of the machine in transferring input force to the output force. Ideal mechanical advantage is based on the design and geometry of the machine, while actual mechanical advantage accounts for real-world limitations and performance.
They can't uless some parts are hidden from inspection.
To gain a mechanical advantage. In other words, to do something you couldn't do without it.
Advantage: Mechanical energy is easily convertible into other forms of energy making it versatile for various applications such as in machines and transportation. Disadvantage: Mechanical energy can be lost due to friction and other factors leading to inefficiencies in mechanical systems.
The mechanical advantage of a machine tells us how much it can multiply or change the input force. A higher mechanical advantage means the machine is more effective at reducing the force needed to perform a task. Machines with a higher mechanical advantage are generally considered more useful because they make work easier to accomplish.
