Describe the steps that a driver should follow driving through deep standing water.
What will be an ideal response?
1. Stay in low gear.
2. Keep your left foot on the brake.
3. Increase RPMs to prevent stalling.
4. Keep light pressure on the brakes for a short distance to dry them out.
5. Release the brakes.
6. Check the rear of your rig to make sure no one is following too closely. Then make a test stop to be certain your brakes are working properly.

a. Enrollar el cable de la plataforma y fijar el estrobo a la agarradera del mástil. b. Realizar el anclaje del cable de la plataforma sobre la polea del piñón del centro de la punta de la pluma, por encima de la polea abatible y de la polea del marco en A. c. Establecer el desplazamiento requerido del brazo ajustando los tensores del cable de soporte posterior. d. Levantar el rodillo del cableado hasta una posición erguida de manera que el cable de la plataforma quede debajo de la polea.

Answer the following statement(s) true (T) or false (F)
1. Use of pressure drop charts based on 60° F water will consistently overestimate the pressure drop in hydronic piping circuits because the water will usually be at higher temperatures. 2. The equivalent length of a component is the amount of tubing, of the same pipe size, that would produce the same head loss (or pressure drop), as the actual component, at the same flow rate. 3. The equivalent hydraulic resistance of an entire assembly is always greater than the smallest individual hydraulic resistance. 4. Determining the flow rates in systems with several parallel branches does not require “number crunching.” 5. Every piping system should be thought of as having an operating cost as well as an installation cost.
