Now, letâs get down to business â the cost! They do offer a 30 day free trial and then after that it is $7.95 a month or $79 a year. After just a few weeks of Nathan playing, I personally feel that the $7.95 a month is totally worth it!
A pendulum is a weight suspended from a pivot so that it can swing freely. When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position.
Weights are used to lower a lampâs center of gravity, thereby reducing the chances that it will tip over if bumped or pushed. They can save floor or table lamps that are near busy thoroughfares from routine damage as, more often than not, children and pets show such pieces little regard and collide with them frequently. Weighted lamp parts are also used to help stabilize top-heavy lamps that may have been built with extensive decorations or oversized arms and shades. We carry several cast iron weights, including ones that have 3-3/8â, 4-Â½â, 5â, 6â, 6-Â¾â 9-Â½â, and 10-Â½â diameters and weigh between 1 and 5 lbs.
