Where is the load arm on a pulley?
The load arm is the radius of the pulley. This is the distance from the fulcrum to the load-carrying side of the rope.
What is the units of ima of a lever?
Length of input arm (input force to the fulcrum) divided by the Length of the output arm (output force to the fulcrum)exampledin/dout=2cm/4cm=0.5in the example the IMA is 0.5
What are the simple machines in a paint tin opener?
Fulcrum I think.
Where is the fulcrum on pliers?
It's the rivet or pin that joins the two main pieces.
What does the mechanical advantage of a first-class lever depend upon?
The advantage of a first class lever is that by using less input force, you get more output force. Teehee!
What is a simple machine with an arm that pivots around the fulcrum?
a lever is what it would be sir/mam
A is a simple machine with a fulcrum an effort arm and a resistance arm?
a lever
What machine would you find a fulcrum?
It's a tool

Where would place a fulcrum of a lever if you had to lify a heavy load?
A fulcrum would be placed as close to the heavy load as possible. This minimizes the lever arm (and thus minimizes the torque) for the load while maximizing the lever arm (and thus maximizing the torque) for the force you must apply.
What are the four parts of the lever?
load arm, effort arm, load, effort, fulcrum!
How much force would a biceps muscle inserted 4 cm from the fulcrum need to hold the arm stationary at a 90 percent angle?
Only a very small force if the arm only has to be supported. What other weights do the arm carry and at what angle does the biceps attach to the fore-arm? What is the distance to the hand from the fulcrum and what is the arm weight (assuming a weight is in the hand and arm weight has to be added to the weight-in-hand)? The length of the hand to fulcrum is also required. There is no such thing as 90% angle: 90 degrees perhaps?
What type of machine would you find a fulcrum?
It's a tool

Place 4n worth of force 0.2m from the fulcrum where would you have to place 2n in order for the lever to balance?
The force is equal to the mass times your lever arm. If 4n is placed 0.2m from the fulcrum, you have 0.8 force units on you lever arm. This would imply that a mass of 2n should be placed 0.4m from the fulcrum in the opposite direction. This would give you 0.8 force units on both sides, thereby balancing the lever.
How is a baseball bat like a lever?
It seems the baseball would be the load, the bat and your arm would together form a lever, and your shoulder would be the fulcrum.
What is the definition of the resistance arm?
The resistance arm is the side of the lever (from the fulcrum to the load) that carries the load.
