Automatic lifting and automatic release, height 1m, 5m and 12m. Test sample is 610mm or 300mm. Drop ball test for dress eyewear: a 0.56 oz 5/8 inch steel ball dropped from a height of 50 inches. Drop ball test for Basic Impact safety lenses: a ONE inch steel ball dropped from a height of 50 inches. High Velocity Impact test for High Impact lenses: a 1/4 inch steel ball hitting the lens at 150 feet/sec.
The steel ball drop test is commonly used in product development to test the durability and impact resistance of materials. It can help engineers and designers determine the strength of a material and make necessary improvements to ensure its reliability and safety in real-world applications. 5. Are there any safety precautions to consider when . Pick up a steel ball by sticking it to a freshly washed finger and drop it into the capillary tube. This works better than using forceps. When dropped into the capillary, the tiny ball is usually stuck at the air-liquid interface. Use a magnet to move the steel ball below the meniscus and to a desired position inside the test solution.Symbol r d D v m g a F f L T Meaning radius of steel ball diameter of the steel ball inner diameter of capillary (terminal) speed of ball drop mass of steel ball gravitational acceleration acceleration buoyant force Net force (gravitational force-buoyant force) lift force drag force density of the steel ball density of test liquid distance of .
