This is the classical problem of cart HORIZONTALLY pulled by a rope that wraps around a pulley and it's pulled VERTICALLY by say, the same mass as the cart (yeah T1 = T2 horizontal and vertical tensions .. = in MAGNITUDE BUT NOT IN...

What force(s) make(s) change of direction in a pulley]]>

Solenoid Problem]]>

Let's say we build the Faraday cage which surround strong radiation such that no radiation can escape to outside world for safety.

What happens on external surface of the Faraday cage in voltage during shielding? Is it fluctuated?]]>

Does the atmosphere cool with altitude due to gravity?]]>

So if it does mean mass, then my ACTUAL weight is 686N!!! lol...

Scale? -- mass or weight]]>

(b) that the electron is (when it is determined) a point

(c) that the repulsion for an electron to itself is therefore r=0

(d) that r=0 would naively end up with infinite force

What is the way out of this problem?...

When r=0 in Coulomb's law; electron self-repulsion]]>

any body please clear my confusion?????]]>

I'm currently making simulations in Solidworks and am confused.

I have to double the force on a pulley and change the dimensions from the original pulley, in order to withstand the new force.

My hypothesis:

If I multiply all the dimensions by the cubed...

cantilever equilibrium problem]]>

Lets say that an object is moving at a decelerating speed(-1m/s) starting on 4m/s towards east and stopped after 4 seconds.

(There are no friction.)

After 4 seconds, the object would have 0 speed, no direction and 0 velocity etc.

Question 1 : Is the...
