Physics Systems
Ball and Ring - Gravesande
A concrete demonstration of the cubic
thermal expansion of a solid. Ring and ball
on chain with 2 wooden handles.
Length of the bar 130 mm, length of the
chain 100 mm. The ball passes through
the ring when cold but will not pass
through after being heated.
Plastic Spring Balance - 1000g
Plastic Spring Balance (Dynamometer)
Range: 10009
In tubular transparent plastic case, with load hook and suspension ring.
The spring mechanism is clearly visible and zero adjustmentis incorporated.
Protection against overload.
Pascal Law Apparatus
