Homework Statement
I have posted the problem in an attachment.
Homework Equations
Aa = Ab + Aab (acceleration at a is equal to the the acceleration of b plus the acceleration of A with respect to B)
Aa = ωob x [ωob x Rob] + [αab x Rab]
Va = Vb + Vab
The Attempt at a Solution...
Would this not be a correct way to go about solving it:
-7.5 i m/s = (ωob x rob) + (ωab x rab)
Then I could use the values for rob and rab that I found in the original post. Then we would have a system of solvable equations with two unknown (ωob and ωab) set equal to their respective i-...
The question in its entirety is:
"For the slider-crank mechanism pictured, determine the angular velocities of links OB and BA if the velocity of the slider at the instant shown is 7.5 m/s to the left."
The answers are ωab = -1.92 k rad/s and ωob = 6.52 k rad/s but I'm very confused on how...

I have attached a picture of the diagram of the problem. I am supposed to determine the angular velocities of links OB and BA if the velocity of the slider at the instant shown is 7.5 m/s to the left.

It was me not understanding what scalar product was in solving this.
When the scalar product of PQ is said to be 60, that means that:
(8*3) + (5*-4)+(2*-Pz) = 60
Solving that simple equation yields the correct answer of -28.
Homework Statement
Given the vectors:
P = 8i +5j-Pzk m
and
Q = 3i -4j-2k m
Determine the value of Pz so that the scalar product of the two vectors will be 60m2Homework Equations
Sure seems like we will need to use the following equation:
P * Q = |P| * |Q| * cos ∅
But I don't recall being able...
