AEE 4263 HW 3

Her foot pivots as a single structure about a single pivot in her ankle. When she stands on tiptoe, her foot pivots about her ankle. As shown in the foot diagram and the free-body diagram below, the forces on one foot are an upward force on her toes from the floor, a downward force on her ankle from the lower leg bone (called the Tibia), and an upward force on the heel of her foot from her Achilles Tendon. Suppose a 61.3 kg woman stands on one foot, on tiptoe, with the sole of her foot making a 25.0 degree angle with the floor, and with the distances are as shown in the figure.

Using the image on the Moment of Inertia Tab, where the following criteria are considered:Assign the values to “Apply torque” = 2 Nm, “Brake force” fr = 0.2 N. “Platform Mass” m= 0.25 kg.Use"radians" for angle units. Write down the values that appear in the graphs of torque, a moment of inertia, and angular acceleration. Then, obtain the other physical quantities by applying the equations of rotational dynamics that correspond to:Time:4.5Applied torque:2 N-mBrake torque:Net torque:Angular impulse:Moment of inertia:Angular acceleration:Initial angular velocity:Final angular velocity:

Chapter 7, Problem 63, there is an 'h' value that is solved when expressing half the width of the Rankine Oval that I am not quite understanding the process by which the value is solved for. Could you break down the process by which h=0.02423 m? It's been a while since I was last in school, so the mathematical method by which 'h' was solved is a little unclear to me.

A pendulum in your house swings from one side to the other in a span of 0.8 seconds. How long is the string that is attached to the mass?

Experiment #2: Acceleration vs. Mass Link https://phet.colorado.edu/sims/html/forces-and-motion-basics/latest/forces-and-motion-basics_en.html In this lab you will determine the relationship between acceleration and mass. Choose an Applied Force at the beginning, and keep it constant for this entire experiment. Set the friction to zero. This will make your Applied Force equal to the net force. Record data for five different values of Mass. Graph Acceleration vs. Mass. Graph this in Google sheets(you want a line graph - it should only have one line). Make sure that Mass information is used as the x value Make sure that Acceleration information is used as the y value Add a trendline – see what fits best – linear, exponential, polynomial, etc … Add a copy of you graph below the table Applied Force (N) Mass (kg) Acceleration (m/s²)

Please answer the following question A cigarettes dispenser requires a south African five-rand (R5) coin with a mass of 9.5 g to dispense one cigarette with a mass of 0.2 g. The design of such a cigarette dispenser is based on a helical spring, of negligible mass, which is found to extend 0.1 mm under a mass of 0.2 g. The spring can support a total mass of a coin. As the customer place money on the dispenser, the spring and coin system displace vertically through 4 mm and release. 1.1. Provide a schematic representation of the mass and spring system. 1.2. Calculate the frequency of natural vibration of the dispenser. 1.3. Determine the velocity of the coin when it is 2 mm below its resting position.

For questions 4)r Calculate the velocity of Block B, after collision. can tutor use m1u1 + m2u2 = m1v1 + m2v2 and u1 – u2 = v2 – v1 to do ? as it is a elastic collision and my lecture need us to use this two equation for elastic collision to solve the velocity

The amount of time it takes for a pendulum to swing “to-and-fro” through one complete cycle is called the “period” and is calculated using the following equation:       where T = period in seconds, I = mass moment of inertia, m = mass of pendulum in kilograms g = gravitational acceleration, 9.8 m/s2, h = effective length of pendulum in meters   What is the appropriate unit for I if the preceding equation is to be homogeneous in units? Please show all of your work.

In the movie Back to the Future, Marty travels back in time to 1955. In 1955, the only available light bulbs in the United States were incandescent bulbs. Assume that last year, you traveled back in time to 1955 and changed all the light bulbs in a single average American household (45 light bulbs) from 75-watt incandescent bulbs to the corresponding 17-watt LED bulbs. The estimated usage is 3 hours per day , at a cost of $0.11 per kilowatt-hour . Based on energy cost alone - not considering the cost to replace any light bulbs and not considering any changes in energy cost with time - how much money in dollars would this household have saved over a 66-year time span (from 1955 to 2021) by changing from incandescent to LED bulbs?

A sliding block C moves along a horizontal line Q2C. A rotation arm Q2B is 4 feet & 3 in. long and rotates around a center Q2. The connecting rod BC is 8 feet long. This rod is extended to D, making BCD 11 feet & 9 in. long. (a) Make a drawing of this linkage and (b) trace the path of D while the arm makes 1 complete revolution CCW. (c) Locate points for each 15 deg movement of the arm Q2B, beginning with Q2B coinciding with Q2C.

Zorch, an archenemy of Superman, decides to slow Earth’s rotation to once per 29 h by exerting a force parallel to the equator, opposing the rotation. Superman is not immediately concerned, because he knows Zorch can only exert a force of 4.15 × 107 N. For the purposes calculations in this problem you should treat the Earth as a sphere of uniform density even though it isn't.   a. How long, in seconds, must Zorch push with this force to accomplish his goal? (This period gives Superman time to devote to other villains.)
