Hi!
I believe these all are going to be correct, but I am not 100% sure. I encourage you to see if you can actually achieve some of these tasks by creating your own database centralised around the object-oriented model. =)
Answer:
(i) The rotation speed must stay the same.
(ii) The rotation speed must increase.
(iii) The rotation speed must decrease.
Explanation:
According to Equation
10.10, the angular speed must therefore vary as the laser–lens system moves
radially along the disc. In a typical CD player, the constant speed of the surface at
the point of the laser–lens system is 1.3 m/s.
In a real machine, the AMA is always less than the IMA. The Actual Mechanical Advantage (AMA) will always be lower than the Ideal Mechanical Advantage (IMA) because of friction loss. Which can't be measured through input and output of forces in the machines.
