The level of a common steelyard without hook connections weights 7kg and acts at 5cm to the left of the fulcrum. The hook which carries the load,weights 4kg and is also attached on the left-hand side of the fulcrum at a distance of 12cm.if graduation mark 72cm from the fulcrum reads 50kg. Find (a).the weight of rider (b). How far is the zero graduation from fulcrum (c).What is the movement of riderper kg of graduation?
True or False 1. The load, P, in the experiment on the mechanical properties of chocolate, can be calculated by dividing mass with the acceleration due to gravity. 2. In the three-point bend test for the flexural stress of chocolate, the stringed-cup containing the coins is placed at both ends of the chocolate instead of at the center. 3. In the formula for the computation of the flexural stress of chocolates, W denotes the weight of the coins used 4. Zinc is a better sacrificial anode for iron than nickel. 5. Flexural strength determination using the three-point bend test can be done to other solids besides chocolates. 6. In the experiment on the mechanical properties of chocolate, the flexural strength of the chocolate can be affected by the ambient temperature and the humidity of the testing area. 7. Bending stress is also known as flexural stress. 8. The test used in observing the mechanical strength of chocolate is the three-point bend test. 9. The flexural strength of…
