IN THE ARRANGEMENT A ROD OF MASS M IS HELD BT 2 SMOOTH WALLS ALWAYS PERPENDICULAR TO THE SURFACE OF THE WEDGE OF MASS m. ASSUME ALL AREAS FRICTIONLESS FIND THE ACC OF BOTH THE BLOCKS

Conjurer

Just make both of them move by a small distance and double differentiate to get relation between their accelerations. Rest is simple.

paulparthapratim2

step1. identify constraint dirn for the 2 bodies in Q

step2. draw the dirn of motion along the dirn reqd.

step3.assume that the bodies r moving by x₁ , x₂ etc.

step4. based on the constraint, work out the reln btw the distances moved by the bodies.

step5.Based on this reln. express the relationship btw accln.

I DONT WANT THE RELATIONSHIP BETWEEN THE MASSEES
I WANT THE ABSOLUTE ACCLERATION

PLS SOLVE

look...The components of velocity of the wedge in the direction of the Motion of the block are equal..hence we get a relation like the ratio of those two velociies is tan theta

ninadroxxx

I mean You get a constraint equation

The velocity component of The block in the direction perpendicular to the wedge is equal to the velocity component of the wedge in the same direction..otherwise the block wud go inside the wedge :P

using tht you can proceed .. rate if found useful :)

HOW MANY TIMES WILL I TELL
THAT I WANT ABSOLUTE ACCLERATION
NOT THE RELATION BETWEN THE MASSES

PLS EXPERTS HELP

ENOUGH IS ENOUGH
I HV POSTED THIS SUM FROM PAST 5 DAYS AND I DONT EVEN GET A REPLY FROM A SINGLE EXPERT

computer001

is there any wall which is touching the wedge??

anki016

hey can u plz post da answers

BALGANESH

is @ the angle of inclination

computer001

assumptions:

from ur dig it looks lik the wedge can move only downwards

variables:

let me call angle of inclination of wedge as @ ,its acc as a1(downwards)..let acc of the rod be a2(perpendicular to the wedge)..the normal force between them is N

method:

now it is direct tht the 2 acc are related as

a1=a2sec@-----(1)

now for rod:

Mgcos@-N=Ma2---(2)

for wedge:

mg + Ncos@ =ma1---(3)

solve
