C)If both cyclists have 170 mm cranks on their bikes, what will be the mechanical advantage (considering only the movement of the feet with a constant force for walking and riding), in percent, that each rider will have achieved over walking the same distance? (This can be found by dividing the distance wallked by the distance the feet move in riding.)

Calculate the magnitude of the resultant joint force at L5/S1 joint for the stoop lift. The worker has a height of 1.8 meters and a mass of 84 kg. The box has a mass of 30 kg. - Assume that the back extensor muscles have a line of action parallel to and 5 cm posterior (on the back side) to the trunk. - Assume the hands are at the center of the box. - Use the following masses and COM locations to calculate the moment at the L5/S1 joint - Note: the body masses and COM positions for the parts of the body are not in kg or cm. They are % of the whole body mass/% away from L5/ S1 joint. You need to convert these percentages to kg and cm. - Only consider the FBD and forces for one arm. Assume each arm holds 15kg of the box weight

Please give a complete solution in Handwritten format. Strictly don't use chatgpt,I need correct answer. Engineering dynamics

Please show work

What is the weight of the car in Newtons?

Please Explain the answer,Thanks

C Dynamic Analysis and Aeroelasticity SECTION B Answer TWO questions from this section ENG2012-N The moment of inertia of a helicopter's rotor is 320kg. m². The rotor starts from rest and at t = 0, the pilot begins by advancing the throttle so that the torque exerted on the rotor by the engine (in N.m) is modelled by as a function of time (in seconds) by T = 250t. a) How long does it take the rotor to turn ten revolutions? b) What is the rotor's angular velocity (in RPM) when it has turned ten revolutions?

● Weight of forearm = 1.6kg ● Center of mass (COM) = 18cm from elbow ● Weight of load held: 15 kg ● Forearm length: 36cm a) What is the force of the forearm (in N)? b) In what direction is the force of the force of the forearm? Positive or negative c) Demonstrate how you found the force of the forearm d) What is the force of the load (in N)? e) In what direction is the force of the load? F) Demonstrate how you found the force of the load

Please show everything step by step in simplest form. Please provide the right answer exactly as per the Question.  Please go through the Question very accurately.

At 250C, the interfacial tension between water and n – octyl alcohol is 8.50 dyne/cm. if the surface tension of n-octyl is 27.53 dyne/cm and that of the water is 72.75 dyne/cm, predict whether water spreads on the alcohol by calculating a) Work of cohesion of n-octyl b) Work of adhesion and c) the spreading coefficient of water on the alcohol. Will alcohol spread on water?

I Review Learning Goal: Part A- Vertical impact To calculate displacement and stresses due to vertical and horizontal impact loads. A 10-kg block is dropped from 1.5 m onto the center of a simply supported beam with a length 3 m. The beam has a square section with side length 6.5 cm. The material has E = 200 GPa . What is the maximum deflection? When an object strikes a structure that responds by deforming in linear elastic fashion, the object comes to rest when the structure has undergone maximum deflection. At that moment, the structure's strain energy must equal the sum of the energies before the impact, including both the object's kinetic energy and its gravitational potential energy. Express your answer with appropriate units to three significant figures. > View Available Hint(s) When an object falls from rest onto a structure, the object's gravitational potential energy is converted into strain energy in the structure. The total strain energy in the structure at the point of…

Which of the following would Newton's first law alone NOT account for?     1)  Passengers on board an elevator undergoing uniform motion can't tell that the elevator is really moving.   2)  A passenger leans forward in her seat when the car's brakes are applied.   3)  During launch, astronauts feel that they are being pushed back into their seats.   4)  No matter how hard you push against it, the boulder would not move.   5)  A rocket accelerates upward from a launch pad and the engines' thrust overcomes gravity.
