Please show step by step solution.

c) What is the minimum force needed to lift the load, if it is 6 feet from the fulcrum and force is applied 3 feet from the fulcrum? /4 Assume a class 3 lever. 5. A lever 9m long has its fulcrum at one end. An object with a mass of 60kg rests on the lever, 2m from the fulcrum. Calculate the force in Newtons required to lift /4 the object. 6. Calculate the MA and output force of the brake pedal lever in the diagram. 14 MASTER CYLINDER FULCRUM 3IN. Output Force = ? 13.5 IN LEVER 10-LB FORCE8. 10 lb of force is applied to the clutch pedal, the distance from the pedal to the fulcrum is 36cm and the distance from the fulcrum to the master cylinder connection is 9cm. /14 The hydraulic system increases the force applied to it by a factor of 5 (5x). The clutch fork has an input arm of 32cm and an output arm of 18cm. Clutch master cylinder Fout Pedal Fout Hydraulic line Clutch slave Clutch cylinder fork Calculate and answer the following (use the additional page to complete your calculations): HINT - make a data list for each section/lever before doing calculations. PROVIDE STATEMENTS a) Clutch pedal MA (3 marks) b) Force applied to master cylinder (3 marks) c) What class lever is the clutch pedal? (1 mark) d) Input force to clutch fork lever (2 marks) e) Clutch fork lever output force (4 marks) f) What class lever is the clutch fork lever? (1 mark)7. Piston that has a mass of 0.5kg moves from TDC to BDC in a cylinder with a stroke of 25cm. the piston completes 1 stroke every 0.5s, and has a final velocity of 9 m/s at BDC. The crankshaft throw provides a MA of 30. TDC Piston 25cm Connecting BDC Rod Calculate the following - NO STATEMENTS NEEDED: a) Weight of the piston (1 mark) Crank Pulley Crank Throw b) Total velocity (1 mark) c) Acceleration of the piston (1 mark) d) Force applied by the piston to the crank throw (1 mark) e) Output force at the crank pully (1 mark)3. If the mechanical advantage (MA) = 0.25, how many pounds of force do you need 13 to put on the effort arm, in order to lift a box which weighs 500 pounds? 4. A plank 10 feel long is used to lift a load of 200lb. (Hint - draw out lever diagrams for each scenario) a) What is the minimum force needed to lift the load, if it is 3 feet 14 from the fulcrum? Assume a class one lever and 10 feet between applied effort and load. b) What is the minimum force needed to lift the load, if it is 3 feet /4 from the fulcrum? Assume a class two lever and the fulcrum is 1 foot from the end
