You are developing a hybrid motorbike using a 2-hp, 2-stroke gasoline engine to drive a generator that powers an electric motor. There is a small lead acid battery used for storing energy. The thermal efficiency of the engine is 25%. The generator is 60% efficient. The electric drive motor is 50% efficient. The battery storage system is 75% efficient. (a) With battery system by-passed, what is the power delivered to the wheels? (b) Power delivered using batteries?

For my assigment, I was asked to design a electric motorbike that has a peformance equal to Honda CBR1000 Fireblade which has a petrol engine. A part of the the assignment is to calculate " An estimate of maximum Power your new motor will need to generate to match the Honda’s performance." I can make the assumption, apart from changing the motor, everything else is going to stay the same so the fairing,the rider and etc they're gonna be the same for the two bikes. So can you please tell me how I can calculate that which information would I need ?

What trigonometric identity may be used to summarize an equation for calculating tension force (the long equation you'll use before replacing the values)? What do you think the role of mass is in determining the net acceleration of an item rolling down an incline? Friction is a significant factor. Why is the normal force no longer equal to the weight of all things on an incline?

Analysis and Interpretation of vertical Ground Reaction Forces. In this study, a volunteer was asked to walk on two force platforms under two different conditions. Condition 1- Normal Walk (NW), condition 2 - walking over an obstacle (ObsW). The right limb was the one to step on platform 1 in both conditions. The force platforms were used to measure the vertical ground reaction forces on the right limb. Data was collected on Vicon (Nexus) software and the attached graphs ( mean NW/ObsW, Mean (+-)1SD NW/ObsW) were created. Analyse ,Interpret the graphs and make a conclusion of the result attached.

The figure shows the biomechanical model of a sprinter's foot just before starting a race. 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, FJ. Also indicate what type of lever it corresponds to and the MA (mechanical advantage) ratio for the configuration shown.

If M = 1.5 kg, what are the tensions in string 1 and string 2?

For the purposes of this question, we will make a simplifying assumption that the only muscle that participates in lifting the arm laterally in abduction is the deltoid muscle. Assume that the insertion point for the deltoid on the humerus is 10 cm from the glenohumeral joint and line of action for this muscle (and all of its components together) is 10° from horizontal when the arm is at 90° abduction (straight to the side). You can assume that person has a body mass of 80 kg. The arm is 55 cm long, and the mass of the arm is approximately 5% of total body weight. Assume that the mass of the arm acts at about 40% of the total length of the arm (on the more proximal side). 0 = 10° 10 cm 55 cm Figure 1: Position and dimensions of the arm in abduction. A) Using this information, calculate the load (N) on the glenohumeral joint when there is no weight in the hand. What is the percent body weight of this load? B) Repeat the calculation when the hand is holding a 2 kg mass. Assume that 55 cm…
