sorry, I am referring to a theoretical number. is a general question

Hi all, I will like to check if I need to balance an out of balance shaft, why is the minimum number of mass block = 1 Is it because i can place the mass on the opposite end of the unbalanced mass at the same distance r away from the axis? and how many are required to dynamically balance the...

thanks, but i don't get what u mean

does anyone why does wind up toy only works when it is being rotated in one direction? i cnat find any answer on9 >_>

Some mechanism to work on 1. Does anyone know why does the wind up toy only allows rotation in one direction? cause i have to think of a mechanism that Allows rotation in one direction CAN’T use ratchet & pawl i am trying to build the idea upon the wind up toy ._. next up i...

i foudn this drawer in my school lab, where we keep all those tools beside the machine. basically, just hold a button and then you can open the drawer..this is an assignment under introduction to engineering. somehow a bit of mechanics caused we were taught cams,belts all this to start with it...

recently, i saw this drawer where you have to press something on a part of the drawer then you can take the things inside the drawer. if not, it is impossible to open the drawer. May I know what kind of mechanism is behind it? secondly anyone got any idea on how to design a mechanism that...

so what kind of mechanism do you suggest cause i really don't get what you mean :(

I had to do this based on the information i learned such as cams,linkages for eg. most probably it should just be a part...

Designing Mechanism -- Updated Anyone got any idea on how to design a mechanism that… ◦Translates rotational motion (clockwise OR anti-clockwise) to linear motion ◦Linear motion ONLY to the right ◦Upon release, the mechanism returns to its initial state

anyone can tell me how to draw the v-t graph. i think i need to interpret from there ._.

Am i right to say the lift is at rest thn it move down and then up again as the mass increased till 11x grams

can u guys care to explain me why?? i want to know the theory ._>

A 100g weight resting on a scale took a ride in a lift. From the video clip, determine whether is the lift going up or down based on Newton’s Laws of Motion and sketch the kinematics profile (v-t graph) of the lift carriage. any idea??
