Economy Force Table

(1 customer reviews)

Equipped with a large, 40cm diameter tabletop, a 3cm thick support column and a heavy cast base with leveling screws, this force table can be a workhorse for any basic physics lab. The durable polymer tabletop carries an angle scale with 0.5° divisions, marked every 10° in both rotation directions. Four table-clamp pulleys are included, each has a circular cutout with a fiducial mark for accurate angle measurements. Four sets of slotted masses, each 150g x 5g including hangars, are supplied with the table. The slotted masses have a keyhole pattern which secures them during adjustments. The cords include split rings for easy connection, allowing three-force and four-force equilibrium arrangements to be rapidly constructed. Includes bubble level. The table is 41cm high.

Sturdy Force Table
Reviewed By: Stefanie (Merced, CA)
Pros: 1. I was definitely impressed with the evident durability of this force table. 2. I also like the keyhole slotted masses; they will not slide off the mass hangers. 3. The top and base may be easily unscrewed from the post for storage. Cons: 1. The pulleys are not low friction; I replaced ours with the Pasco Super Pulleys since we had extras and they are low friction. 2. When the pulleys are installed, they cover the 0.5-degree markings on the scale. The Super Pulleys do not cover the 0.5-degree markings and are etched for easily reading the scale. 3. The string came pre-cut and tied to the rings. However, they were just a little too short (the mass hanger touched the pulley... not as long as in the picture), so I replaced them with slightly longer string. Overall, the pros far outweigh the cons. This table is heavy, sturdy and I expect it to last for years to come. Pulleys and string are minor parts which are easily replaced; if this is done (which I recommend), this is an excellent Force Table.
