My office hours will be held in 3745D CCRB (the conference room) the following days and times:

Monday November 14th 1-3pm

Monday November 21st 1-3pm

Friday December 2nd 11-1pm

Wednesday December 7th 1-3pm * Will be held in my office (1230E CCRB)

See you there!

Rationale

MVS 110 consists of three conceptual modules (Biomechanics, Exercise Physiology & Motor Control) each taught by a different instructor. Each module is made up of twelve lectures and one exam. The students remain in the same course section (and classroom) for the entire semester, while the instructors rotate among the course sections. This current module will be an introduction to Biomechanics.

Course Assessment

Each module is worth 1/3 of the total grade. For this particular module, assessment will be based on:

Homeworks are due at the beginning of class, none will be accepted once the class has started. The final exam occurs on the last day of classes for the module.

Poorly presented homeworks (ex. messy) will NOT be accepted

4a) One of my regular activities is washing dishes. I do this in a sink filled with hot soapy water using either a scrub brush (with a long handle), a sponge or a dish cloth.

4b) I will measure the maximum forward lean of my back (the angle between my back and pelvis) as well as how far away from my body I hold the dish I am cleaning.

4c) To measure the angle of my back, I will be using a goniometer with one arm attached to my back and the other attached to my pelvis. To measure how far away I am holding the dish, I will use motion capture. I will place a video camera straight above my head (and the sink) and record my movements in a 2D plane. I will then watch the video and measure the distance using the captured image.

4d) Two of my common complaints while washing dishes is that my lower back and my shoulders hurt. I will take these measurements using the three different washing tools (scrub brush, sponge and dish cloth) and then compare the angles and distances using these tools. The larger the maximum forward lean of my back, the more likely my lower back will hurt while doing dishes. The further away the dish is from my body, the more likely my shoulders will hurt while doing dishes. I will compare these two measurements using all three tools and find the tool which minimizes both of these. This will reduce the risk of a serious dish washing injury.

1. Give two (2) reasons why the can stays balanced on its edge.
2. Sketch the can balancing on its edge and indicate the important components of balance. Hint: make sure your drawing has the can balancing! (5pts)
3. Select a pose which you can maintain for at least 30 seconds.
   1. Make a sketch of this pose (a stick figure will suffice). (2pts)
   2. Indicate on your drawing the important components of balance (draw and label). (3pts)
   3. Describe 2 reasons why this pose is stable/unstable. (2pts)

Please:

• make sure the drawings take up at least 1/3 of the page
• use a ruler for straight lines
• staple sheets together
• write you name in the top right corner of the first sheet of paper
• messy homeworks will not be accepted!

1.  
   
   1. Your height (m)
   2. Your mass (Kg)
   3. Your weight (N) consider gravity to be 10m/s2

   (1pt)

2.  
   
   1. Calculate the length of your foot using the anthropometric table (Show you work)
   2. Measure the length of your foot
   3. Calculate the mass of your thigh using the anthropometric table (Show you work)
   4. Calculate the mass of your head using the anthropometric table (Show you work)

   (4pts)

3. Using your measured foot length and assuming that your CoM is at the midpoint of your body (half of your height), calculate your ankle angle at you maximum forward lean. (Assume that the knees and hips are not bent).
   
   1. Draw a very simple diagram of this pose (1pt)
   2. Indicate the three important concepts of balance (1pt)
   3. Calculate the ankle angle. (Show all your work) (4pts)
   4. Describe how you could measure your actual ankle angle at your maximum forward lean. What tools would you use? (2pts)
4.  
   
   1. Describe one of your activities (hobby, sport, job, etc...) for which you could conduct a kinematic analysis. (1pt)
   2. Describe what measures you would take (at least two) (2pts)
   3. What tools you would use (2pts)
   4. How can taking these measures benefit you. (2pts)
