Question

Thw two springs are identicle, with unstretched lengths of 250mm. Suppose that their spring constant "k" is unknown and the sum of the masses of blocks A and B is 10kg. Determine the value of k and the masses of the two blocks.

It is harder than it seems, It just seems as if they don't provide enough numbers to figure it out.

Explanation / Answer

it's simple budy...don't be confuse go through these 2 equations

according to free body daigram of block A.....

K*0.05=(9.81*M)+(0.03*K)...................(1)

according to Free body daigram of body B....

(10-M)*9.81=0.03*K..............................(2)

solving above equations we get,

K=1962 N-m

M=4kg

so Mass of body A=4 kg

Mass of body B=6kg
