A student and enthusiastic programmer. Love learning Physics! And I make android apps as a hobby.

This will make a great and interesting site : Puzzling. Please follow it

Please support Mechanical Engineering. There are many questions on PhysicsSE site related to engineering, which do not get answered because they are off-topic.

Oct25 comment Where does the extra force generated by a lever come from? Now it does matter how long the lever is because the force of the fulcrum cannot make the lever rotate(it is applying torque in the wrong direction), so you need the 1lb of your finger to make the lever rotate, and so you need a long enough lever to make 1lb sufficient. Oct25 comment Where does the extra force generated by a lever come from? Well its like, the lever supports the weight of the load, the fulcrum supports the total force the lever applies downward(force you exert from your hand + weight of the load, i.e. total force of lever + load system), and the ground likewise supports the force fulcrum exerts downward. Oct24 comment Where does the extra force generated by a lever come from? What does "consistently have the same impact mean"? Anyway if you want to look at the forces on the load only, the lever will exert a normal force upward on the load, which in turn will create tension in the lever. So if you use a heavy enough load, the lever can snap apart Oct24 reviewed Edit suggested edit on Does a heavy body move with the slightest force on a frictionless surface? Oct24 revised Does a heavy body move with the slightest force on a frictionless surface? inserted tag Oct24 comment Light behaves as a particle or wave in this thought experiment? secondly, are you saying that no photons will reach the trough at all, if we look at it from the particle view-point Oct24 comment Light behaves as a particle or wave in this thought experiment? You don't need to use a thin strip of metal, you can simply cover the metal plate with paper or something else and expose only the region of the trough.

Sep14 comment Power delivered by centripetal force Note that the velocity can be varied in Case 1 by a tangential impulse(if change in F is sudden) or by an appropriate tangential force(if change in F is continuous) Sep14 answered Power delivered by centripetal force Sep10 reviewed No Action Needed Explicit solutions to 2-d Dirac Equation
