The pedal spindle is threaded to match a threaded hole at the outboard end of the cranks. Multi-piece cranks have a 9⁄16-inch (14.2875 mm) hole with 20 TPI (a diameter/pitch combination fairly unique to this application). One-piece cranks use a 1⁄2-inch (12.7 mm) by 20 TPI hole. French pedal spindles use M14 x 1.25
(14 mm or 0.55 in metric diameter with 1.25 mm or 0.049 in pitch)
threads, and thread loosely into a 9/16 pedal hole. The threading size
is often stamped into the crank, near the pedal hole. The right-side
(usually the drive-side) pedal spindle is right-hand threaded, and the
left-side (usually the non-drive-side) pedal spindle is left-hand
(reverse) threaded to help prevent it from becoming loose by an effect
called precession.[12][13] Although the left pedal turns clockwise
on its bearing relative to the crank (and so would seem to tighten a
right-hand thread), the force from the rider's foot presses the spindle
against the crank thread at a point which rolls around clockwise with
respect to the crank, thus slowly pulling the outside of the pedal
spindle anticlockwise (counterclockwise) because of friction and thus
would loosen a right-hand thread. For a short time in the early 1980s, Shimano
made pedals and matching cranks that had a 1-inch (25.4 mm) by 24 TPI
interface. This was to allow a larger single bearing, as these pedals
were designed to work with just one bearing on the crank side rather
than the conventional design of one smaller bearing on each side.[1http://gengwg.blogspot.com/
https://killer.sh Pre Setup Once you've gained access to your terminal it might be wise to spend ~1 minute to setup your environment. You could set these: alias k = kubectl # will already be pre-configured export do = "--dry-run=client -o yaml" # k get pod x $do export now = "--force --grace-period 0" # k delete pod x $now Vim To make vim use 2 spaces for a tab edit ~/.vimrc to contain: set tabstop=2 set expandtab set shiftwidth=2 More setup suggestions are in the tips section . Question 1 | Contexts Task weight: 1% You have access to multiple clusters from your main terminal through kubectl contexts. Write all those context names into /opt/course/1/contexts . Next write a command to display the current context into /opt/course/1/context_default_kubectl.sh , the command should use kubectl . Finally write a second command doing the same thing into ...
