Re: Simple Machines B/Compound Machines C Question Marathon
What are the general formulas for each of the simple machines?
Never argue with an idiot, they will drag you down to their level and then beat you with experience.
Before you criticize a man, walk a mile in his shoes. That way you'll be a mile away and he'll be shoeless.
You should only create problems, that only you know solutions to.

Re: Simple Machines B/Compound Machines C Question Marathon
IMA of:
Pulley: number of strings supporting the mass
Lever: effort distance/load distance
Wedge: length/base width
Wheel and Axle: radius of wheel/radius of axle
Inclined Plane: Length of base/Height
Screw: Circumference/pitch
Pulley: number of strings supporting the mass
Lever: effort distance/load distance
Wedge: length/base width
Wheel and Axle: radius of wheel/radius of axle
Inclined Plane: Length of base/Height
Screw: Circumference/pitch
Looking forward to anatomy, protein, fossils, and optics (NYS trial) this year!

Good job, except in the wedge, what do you mean by length?fantasyfan wrote:IMA of:

Re: Simple Machines B/Compound Machines C Question Marathon
I meant the distance from the middle of the base to the tip

Re: Simple Machines B/Compound Machines C Question Marathon
Then I think it's right for a wedge then. However, for the inclined plane I think it's wrong, and should be length of incline over height (http://hyperphysics.phy-astr.gsu.edu/hb ... ac.html#c1)fantasyfan wrote:IMA of:

What are some ways to increase the stability and balance of a first class lever?

Re: Simple Machines B/Compound Machines C Question Marathon
More importantly, what can be changed to increase accuracy for calculations (much like the device portion of the competition)?
