Q2/ A former student of mechanics wishes to weigh himself but has access only to a scale A with capacity limited to 100 lb and a small 20-lb spring dynamometer B. With the rig shown he discovers that when he exerts a pull on the rope so that B registers 19 lb, the scale A reads 67 lb. What is his correct weight? B A

The platform scale consists of a combination of third and first class levers so that the load on one lever becomes the effort that moves the next lever. Through this arrangement, a small weight can balance a massive object. If a 3kg counterweight S is used to balance a 120kg load L, what is the value of 'x'? Draw all pertinent FBDs. Use g=9.806 m/s2.
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…
Q.1) Draw a Free Body Diagram for each object indicated below. Include values for known forces and moments and variables for any unknown quantity. Use dashed lines to include any dimensions or angles when appropriate. Any two-force member should be modeled using a single force in the appropriate direction. (a) Draw member ABD assuming all members have negligible mass. B, C, and D are all pin connections. T 1 in. -3 in. A 50 lb 2 in. B -5 in. D 3 in. (b) Draw member ABC. Assume the mass of ABC is negligible, the mass and size of pulleys C and D are negligible and the pulleys are frictionless. A represents a pin connection. Welded 0.5 m 1200 mm-600- D mm 0.4 m B 300 mm 0.4 m A 400 kg uniform steel beam is welded to the wall at A. An 80 kg man stands on the beam while holding the end of a cable that wraps around a pulley having negligible friction and negligible mass. Treat the man as a rigid body with two feet contacting the beam. (c) Draw the steel beam and man as one FBD. (d) Draw the…

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?
