An extra credit assignment for my Statics class, this is my earliest example of good creative Excel work. Shingles - Asphalt - 1 layer: 2. The span of any wood beam depends on many factors, such as type of wood, weight of the load and overall size of the beam. Even though there is lateral movement at the brace point, the load increase can be more than three times the unbraced case. It will be found that selection of the reference section of a cantilever beam at the fixed end for construction of the moment diagram by parts usually gives the minimum number of areas. Once all values are entered, select the image that most resembles the situation of concern and click the "Submit for Calculation" button for results. The actual weight of equipment to be supported, applied as a concentrated load at point of application (screed rail, etc. 63 Note that roofs exceeding an angle of 30 degrees may reduce the ground snow load. 0 MT Width.
