Different crank-pedal systems and chainring shapes have been proposed in an attempt to alter the pedalling motion by varying the crank arm length, the position of the chainring rotation axis, or the radius of the chainring during a pedal revolution (for a review, see Bini and Dagnese, 2012; Faria et al., 2005).
A few of the partners' completed projects include Arrow Haircuts and NuvoNivo on Hargett Street, Runologie and State of Beer on Hillsborough Street, Trophy Brewing Company on Maywood Avenue and Crank Arm Brewing Company on West Davie Street.
A direct-drive, freewheeling hub joins the crank arm axis with the rear-wheel axis, shortening the wheelbase and minimizing the design.
To replace the operator, first take the crank arm off the sash.
where co is the crank angular velocity, T is the crank torque, r is the crank arm length, [F.sub.t] is the tangential crank force, F is the normal force on the pedal and [alpha] is the instant angle.
This twisting action and the resulting rebound (as the crank arm snaps back in the opposite direction) is known as torsional harmonic vibration.
The only remaining parts requiring inspection are those associated with the linkage, crank arm assembly, etc.
"I fashioned a crank arm from a bit of scrap iron, built the handlebar from some rusted BMX acro-tubing, and made the bottom bracket bearings out of an old washing-machine," he said.
The accelerations monitored are factored into the control system computer's algorithm that guides the servo motor positioning of the crank arm and spring.
