What else can I help you with?
Using a crowbar you apply an effort force of 30 N to pry open a window that has resistance force of 600 N so What is the mechanical advantage MA of the crowbar?
MA= Resistance force / Effort force = 600N / 30 N MA = 20N
If a wheel and axle has a mechanical advantage of 3 what effort force is required to move a load of 30 N?
The effort force required would be 10 N. This is because mechanical advantage is calculated as Load force/Effort force, so the Effort force = Load force/Mechanical advantage. In this case, 30 N (Load force) divided by 3 (Mechanical advantage) equals 10 N for the Effort force.
If you have to apply 40 N of force on a crowbar to lift a rock that weights 400 N what is the actual mechanical advantage of the crowbar?
It would have a mechanical advantage of 20, thus dividing the resistance force of 600N by the effort force of 30N.
What is the idea mechanical advantage of a wheel with a diameter of a 30 cm fixed to an axle with a diameter of 4 cm if the axle is turned?
The ideal (not idea) mechanical advantage is 30/4 = 7.5
What is a second class lever mechanical advantage if it takes only 30 pound to lift a 120 pound bag of soil?
If a force of 30 pounds lifts a load of 120 pounds, it sounds to me like the mechanical advantage must be 4, regardless of what kind of contraption you used to accomplish it.
What is the ideal mechanical advantage of a wheel with a diameter of 30 cm fixed to an axel with a diameter of 4 cm if the axel is turned?
It is 30/4 = 7.5
What is the mechanical advantage of a machine that requires 30 N input force to produce the input force to produce 15 N of output force?
The mechanical advantage of this machine is 0.5. This is calculated by dividing the output force (15 N) by the input force (30 N). This means that the machine reduces the force required by half to produce the desired output force.
How does the mechanical advantage with input and output distance compare with the mechanical advantage using input and output force for the incline plane?
Mechanical advantage of an inclined plane: Ratio of force overcome by nature of weight of mass ( mass * acceleration due to gravity) to force required to move it. Example: ( take g as 10 (m/s)/s ) A mass of 10 kg is on a 30 degree incline , which generates (10 * 10) 100 newtons vertically down, the vector of this parallel to and down the slope is 100 * sin 30 degrees = 100 * 0.5 = 50 newtons which is the force required by the input force, so the ratio = 100:50 = 2:1 which is the mechanical advantage. This is also the ratio of vertical distance travelled by load : distance travelled up the slope
What is the mechanical advantage of machine that requires 30 N of input force to produce 15 N of output force?
The mechanical advantage is the ratio of the output force to the input force. MA = output/input (output force divided by the input force) For the example, 15N/30N gives the MA as 0.5 (one half).
What is the mechanical advantage of a machine that requires 30 N of input force to produce 15 N of the output force?
The mechanical advantage is the ratio of the output force to the input force. MA = output/input (output force divided by the input force) For the example, 15N/30N gives the MA as 0.5 (one half).
What is the mechanical advantage of a machine that requires 30 n of inpute force to produce 15 n of output force?
The mechanical advantage is the ratio of the output force to the input force. MA = output/input (output force divided by the input force) For the example, 15N/30N gives the MA as 0.5 (one half).
How can you increase Mechanical Advantage of Pulley Up to 30 or more using less than 11 pulleys?
connect the rope/line to a fixed axle and have a large lever turning this. Distance traveled by effort will be greatly increased. Your pulley system is most likely over 50% efficient so your load will overhaul unless a brake is used to keep the line from running backwards
