The lattice boom is designed to take winds of up to 20 mph. from the side plus a full rated load, plus a direct side load equal to what percent of the rated load? - 2% The part of the load chart governed by stability is based on what percentage of capacity while a crawler crane is working over the side quadrant? - A. 75% The most unstable working quadrant for a crawler crane is the; - Side What type of capacity is listed on a crane load chart? - Static If the manufacture of a particular cr...

What is lattice energy? - The energy required to completely seperate a mole of a solid compound into its gaseous ions. They have positive ∆H values. What is the trend of lattice energy? - Lattice energy increase as the charge of the ions increase and their radii decrease. How do you find lattice energy? - First, find the charges of the ions in the compound. Second, place them in order of increasing or decreasing based on charge. Third, if the charges are the same look at the position on ...
