1. When a SMALL EGG is dropped onto the piece of 1-inch foam, from which height did the egg break entirely? Select all that apply.
a. When dropped from 1 meter
b. When dropped from 5 meters
c. When dropped from 10 meters
d. Nonsense! the small egg never broke when dropped onto 1-inch foam

2. When a small egg is dropped onto the piece of 1-inch foam, from which height did the egg fracture but not break? select all that apply
a. When dropped from 1 meter
b. When dropped from 5 meters
c. When dropped from 10 meters
d. Nonsense! the small egg never broke when dropped onto 1-inch foam

3. When a LARGE EGG is dropped from a height of 10 meters, upon which landing surface did the egg break entirely? select all that apply.
a. When landing on the hard floor
b. When landing on the 1-inch piece of foam
c. When landing in the box filled with foam pieces
d. Nonsense! the large egg never broke when dropped onto any of the landing surfaces from a height of 10 meters

Background: This interactive involves observing the results of dropping an egg onto a surface. The size of the egg, the height from which it is dropped, and the characteristics of the landing surface can be varied. The effect of variation upon the safety of the egg will be examined. The interactive is based on the impulse-momentum change theorem. The question s target a Interactive ability to reason scientifically.

4. In a two – story building, an exterior column is to be designed for a service dead load of 1000 KN, maximum live load of 1500 KN, dead load moment of 60 KN m, and live load moment of 90 KN m. If the column dimensions will be restricted to 400 mm x 500 mm, fc’ = 27.6 MPa, and fy = 414 MPa, calculate the required column reinforcement

A soil has the following properties: pH 8.6; ESP = 18%; CEC = 25 meq/100g; CaCO3 = 2%. (Question 32, Chapter 3 in text), acre furrow slice (afs) = 2 x 106 lbs. soil.

a. Calculate the SAR

b. A test lab recommended 4,300 lbs gypsum/afs. Calculate the final ESP if the grower followed the recommendation.

c. If the grower added elemental S instead of gypsum, calculate the final CaCO3 content

1 point) (Once you have their money, never give it back.) An apartment complex on Ferenginar with 250 units currently has 187 occupants. The current rent for a unit is 935 slips of Gold-Pressed Latinum. The owner of the complex knows from experience that he loses one occupant every time he raises the rent by 2.5 slips of Latinum. Since "profit is its own reward", the owner wants to maximize his profit so he asks for our help, even though he knows that "free advice is seldom cheap". What should be our recommendation for the optimal rent? slips of Gold-Pressed Latinum

Q1: Explain why Engineering Controls (Barriers / Isolation) are more effective than Administrative Controls for reducing accidents? Is this true in ALL cases?

Q2: Is it easier to audit and validate the ongoing safety of a system that uses Engineering Controls than one that uses Administrative Controls?

Q3: How do you identify the candidate components or functions for the an FMEA? How do I know I have ALL the necessary components or Functions?

Q4: Explain why a Preliminary Hazard Analysis (Preliminary Risk Analysis) cannot be used to calculate the overall safety of the design (total likelihood x total consequences)? Does an FMEA solve this problem?

Q5: Should my team use the Severity, Occurrence and Detection table from an industry recommended standard, or should my team generate their own? Does my business manager / my customer need to agree to these tables? Why should I include the Severity, Occurrence and Detection tables in my design document recording the FMEA analysis?

Q6: One of the differences between a Preliminary Hazard Analysis (Preliminary Risk Analysis) and an FMEA is to assess the Detectability of a failure. Why would analysing this lead to a safer / more reliable design?

Q7: "Systems are analyzed to identify their hazards and those hazards are assessed as to their risks for a single reason: to support management decision-making" [NIOSH, 1998]. Name three important management decisions that are 'documented' in the course of performing a fully completed FMEA.
