It is possible to increase the resistance to acceleration due to flywheel inertia either by increasing the dimensions of the flywheel or by increasing the ratio between crank angular velocity and flywheel angular velocity (gear ratio).
Unfortunately, the crank length was not adjusted to the body dimensions of the subjects, and the value of Vopt was probably underestimated in small and young subjects.
It is a function of the crank angle position.
As shown in the paper, all torque components are functions of the crank angle; consequently, their exact calculation necessitates the knowledge of the crank angle versus time function.
Counterbalance Torque, on the other hand, varies simply with the sine function of the crank angle.
Timing belt pulley is located onto the stub-end-hole of the crank shaft.
Svinos used, instead of the crank angle, θ, defined in API Spec.

The average crank cycle (for all variables) was calculated by interpolation of the crank angle variable data to 360 samples, i.e., 1 sample per degree crank angle (Ettema et al. 2009).
Unscrew the crank puller slightly, until the "pusher" part of the crank puller is recessed within the threaded part of the tool.
