EQUINE (RE)ENGINEERING LICENSING EXAM

You may choose 3 of the 4 questions below to answer. We will choose 1 of the 4 questions to be graded. (Examiner: Dr. Grace Ann Rosile)

1. A 6" diameter metal-rimmed oval, weighing 1000 lbs, is traveling at a velocity of 20 ft/second.

**Part I: Calculate the thickness of steel required to withstand this force in the toe of your boot.

**Part II: Calculate the resultant psi if this object were to land on a rubber-thong supported foot.

2. Determine the ideal gradient for a roadway to allow the following:

**Part I: a person having a 28"inseam to mount a 15 h horse without stress-related damaging force to the posterior portion of the cotton and lycra interface point.

**Part II: Recalculate this gradient assuming the horse can park out.

3. Explain the anticipated changes in force and velocity of vectors.

Vector A is a fur-covered one thousand pounds traveling at 25 mph at 16 degrees North. Vector B is a fur-covered 6 lbs. with long ears, traveling at 35 mph at 23 degrees East. Vectors A and B will collide in 30 seconds. What will be the resultant change in each vector?

A) Each vector will alter direction equally, by 23 degrees East and North, respectively. No change in velocity is anticipated.

B) Vector B's course will remain at 35 mph but with direction reversed to 23 degrees West, except for the ears, which will still face East. Vector A's course will remain at 25 mph with only a slight alteration to 18 degrees North.

C) One second before impact, Vector A will become airborne, changing direction by 45 degrees with an accompanying 200% increase in speed, thus avoiding collision.

4. Determine structural support necessary in the following situations:

**Part I: How many 4"x4" oak beams are required to support a 30'x48' platform which is covered completely with 1.5x1.5x3' rectangles of dried organic matter, each rectangle weighing an average of 45 lbs?

**Part II: How many incomes are required to support such a structure?
