Okay up next is PSP, 1st Gen without charget , with
SD card, and games loaded, and
headphone extender, glass case and what nots....
questions are simple : 1] As engineers all know point load is infinite. that means if I put point load on something it will break and wither like dried leaves in summer breeze.... even though when I put a ball on table it never breaks HOW COME ???
2] Every motor is made with positive pressure above sea level so what if I take a motor and use it UNDER sea? will it work?
Conditions : make answer as close to real answer but technically correct , Shipping charges from me to you by you.. ( if exceeds 200 INR I will pay the difference)
Ok... Thanks for the giveaway.. here's my entry
Ans 1. Acc. to Newton's 3rd law.. the weight of the ball on the table balances the normal reactionary force provided by the table hence not letting it break. But in case of point load being infinite, the weight cannot be balance by normal reactionary force provided by the table and hence it break and wither like leaves
Ans 2. Yes. the motor will work under the sea.. acc. to bernoulli's law of fluids, pressure diff. across fluid surface leads to rise of liquid in water column.. since the pressure diff. under the sea is much prominent, hence the diff. in water pressure at different points or depth under sea will help the motor to work..
