- What is the mechinaical advantage of the class 1 leverHey there! I have attatched a photo that goes with the question below :) Gears are often connected to each other by a chain. Calculate the IMA of the system below knowing that a bicycle's pedals are connected to the large gear. (You will have to count the gear teeth) 2.7 2.8 0.36 0.4 These are all the possible answers. Thanks!The figure shows the biomechanical model of the foot of a sprinter just before starting a race. You are asked to determine the magnitude of the force exerted on the heel by the Achilles tendon, FH, and the magnitude of the force exerted on the foot at the ankle joint, F.J. Also indicate what type of lever it corresponds to and the reason MA (mechanical advantage) for the configuration shown.
- A device for exercising the upper leg muscle is shown in the figure, together with a schematic representation of an equivalent lever system. Calculate the force exerted by the upper leg muscle to lift the mass at a constant speed.In the shown systems of pulleys, the weight of each box is W=100N. For each configuration, calculate the force that needs to be applied at the free end of the rope to keep the system in static equilibrium. Be sure to indicate the tension forces in the rope. The uppermost pulleys in each assembly are anchored by their orange brackets to the ceiling.What is the mechanical advantage of a nail puller—similar to the one shown in Figure shown —where you exert a force 45 cm from the pivot and the nail is 1.8 cm on the other side? What minimum force must you exert to apply a force of 1250 N to the nail?
- A device for exercising the upper leg muscle is shown in Figure shown, together with a schematic representation of an equivalent lever system. Calculate the force exerted by the upper leg muscle to lift the mass at a constant speed. Explicitly show how you follow the steps in the Problem- Solving Strategy for static equilibrium in(Hint): Applications of Statistics, Including Problem-Solving Strategies.What lever class has the fulcrum situated between the force and the load? a. second-class lever b. fourth-class lever c. third-class lever d. first-class leverHey there! I have a multiple choice question below. Which of the following is NOT true of a lever? -it changes the magnitude of the force -it changes the direction of the force -it rotates about a central axis referred to as the principal axis -it involves a load force and an effort force -there are 3 classes of levers Those are all the possible answers, Thanks! :)
