sir acceleration diagram is by considering the relative acceleration value right which is in rad/sec^2 but here u have considered velocity value which is in m/sec
Tq sir..very well explained

Overall it is nice... Introduction part is very good... Please explain these points 1) Directions ie....CW and CCW 2) Directions ie. why you taken radial component of PQ downwards..? These things can help the viewers a lot Best wishes....

sure. i will explain in my next video. Regarding the second question, the radial component of PQ will be downward or upward.you can take both direction . the point is on which direction it intersect with other line. If you change the direction also ,you will get same answer i mean shape of the diagram may be different but same size only. in the classroom,we ask one batch to follow one direction and another batch willbe asked to follow other direction. on both direction , you will get same answer.

Sir but since angular velocity is constant for link pq it should be constant for qr also .so why we are drawing tangential component for link qr it will be zero only naa?? Sir plzz clear
@icgindia2970
5 жыл бұрын
Aditya Mohanty in pq normally a motor attached to create rotary motion since the motor rotates at constant speed ,here velocity is constant. At qr there is no motor

Oohokk sir I got it so the conclusion is that when angular velocity changes the linear velocity of the point on that link changes due to which tangential acceleration also changes .am I right sir??

How do you know the true acceleration or the tangential acceleration of QR and RS is to the left but not to the right?

Hi i dont understand why a radial acceleration is not zero too for constant angular velocity...pls help
@icgindia2970

Radial acceleration = radius x change in velocity. If velocity is constant then change in velocity is zero. So radial acceleration is zero

Sir I have one doubt if crank is rotating in clockwise direction the while drawing in which direction we have to draw the vectors on acceleration diagram
@vimalbolozubankesri8996

Like for example if crank is rotated in clockwise direction then it's radial acceleration parallel that I know but in which direction we have to draw it's tangential acceleration -left or right

initially in the diagram it is shown radial component of acceleration of PQ towards the centre P, but while you drew the actual one it is shown directed away from centre P?Got that confusion for a long time.Thanks
