51.863. Inclined Plane (Weinhold's) (W. D., Fig. 71 [64]), with polished oak stand, carriage 



and loading pan weighing together 500 g, with 2 tared balance pans of each 50 g . 3. 0. o 



This inclined plane must only be used in conjunction with frame Xo. 51,851 a and pulleys

51.865. Inclined Plane, as No. 51,863, but with a pulley on the upper end. Constructed in 



this manner the apparatus can be used independently 3. 6.

51.867. Plate Glass Slab, Sliding Body and light Balance Pan, for experiments on sliding friction 



(W. D., p. 137 [116]) 0. 8.0 



Tne dull polished glass plate is laid upon the inclined plane so as to afford a uniform bearing 

 surface for the sliding body. The sliding body is of hard wood, and drawing paper is gummed on 

 3 different sized surfaces, two other surfaces being provided with small hooks.
