What will the scale read in these 2 examples?

The incline is 12 degrees. The bicycle weight is 14kg. The cylinder weight is 14kg.

2. Relevant equations

Force of 2nd pulley 'arm' is 1/2 weight

Force on incline is force X sin(angle)

3. The attempt at a solution

A scale is attached with wires to the circumference of the bicycle wheel and the bicycle frame. The line of the wire is at a tangent to the wheel. The measurement on the scale is: (14kg) (sin12) = 2.9kg

Another scale is attached similarly to the circumference of the cylinder, except the scale is attached to a frame mounted to the ground. The measurement of the scale is: .5 (14kg) (sin12) = 1.45kg
