How can competitive livestock evaluation help participants develop life skills?
What will be an ideal response?
In addition to inspiring participants to develop the skills needed to choose livestock wisely, competitive livestock evaluation helps participants learn to think critically and analyze data based on observation. Both are skills needed in life situations. Learning to problem solve and make sound decisions are critical to success in all realms_

A recent graduate who wants to start an excavation/earth-moving business is trying to determine which size of used dump truck to buy. He knows that as the bed size increases, the net income increases, but he is uncertain whether the incremental expenditure required for the larger trucks is justified. The cash flows associated with each size truck are estimated below. The contractor has established a MARR of 18% per year, and all trucks are expected to have a remaining economic life of 5 years. (a) Determine which size truck he should purchase. (b) If two trucks are to be purchased, what should be the size of the second truck?

A sphere of ice, 5 cm in diameter, is exposed to 65 km/h wind with 15 percent relative humidity. Both the ice sphere and air are at ? 1°C and 90 kPa. Predict the rate of evaporation of the ice in g/h by use of the following correlation for single spheres: Sh = [4.0 + 1.21 (ReSc)2/3]0.5. Data at ? 1°C and 90 kPa: , kinematic viscosity (air) = 1.32 × 10?7 m2/s, vapor pressure (H2O) = 0.56 kPa and density (ice) = 915 kg/m3.
