Cenco Centripetal Force Apparatus You are bidding on One Used Cenco Central Scientific Company Centripetal Force Apparatus in Good Condition. BUYER TAKE NOTE:  This is a multiple-quantity listing, the item you receive may not be identical in appearance to the item pictured, but it will be in the same condition.  We have these apparatus in Grey, Blue, and one in Black.  A few of them have had a paper-clip affixed to the weight so as to allow adding additional weight.    The following information is from the Cenco-Physics webpage on this item: Using the sensitive balance between the inertial force on a rotating mass and the elastic force of an extended spring, this unit provides the data necessary to calculate centripetal force. When the apparatus rotates, the centripetal force required to maintain the mass in its circular path is provided by the attached, adjustable-tension spring. At low speeds the spring easily provides sufficient force, but at high speeds it is too weak. The point of balance of these two forces is indicated by a sensitive pointer that’s visible at any speed during rotation. Adjust the speed until the pointer is just opposite the index, so the centripetal force exerted by the spring and the reaction of the mass on the spring are equal. With the pointer stable opposite the index, determine the rotational speed using the revolution counter or meter attached to the rotator (ROTATOR NOT INCLUDED)       ATTENTION INTERNATIONAL BIDDERS: Import duties, taxes, and Customs charges are not included in the item price or shipping cost. These charges are the buyer's responsibility. Please check with your country's customs office to determine what these additional costs will be prior to bidding or buying.
