Chapter 11, Problem 11.2.3P

Determine rotations at all the nodes of the beam and reactions at the supports.  Assume support 1 and 3 are roller and support 2 is pinned,  L1=1.25m, L2=3.75m and w=60kN/m. Please show all working and FBD's where relevant.

۰۹:۲۵ ZV9 HW2-C.pdf Dept: Civil Eng. Kerbala HW2 3rd Year (C) Ex 4-1: The field capacity and wilting point as depth equivalent of soil are 178mm and 102 mm respectively. PAD-60% Calculate the irrigation interval if the water consumptive use is 4.5 mm/day. Ex 4-2: The specific gravity of the soil is 1.41 percentage of water content by weight at field capacity and wilting point are 15% and 7% respectively. a) calculate the equivalent depth of moisture content for 1.2m root zone and PAD 70% at permanent wilting point, at field capacity and for readily available water b) If the crop consumptive use is 18 m/donum/day, calculate: Irrigation interval in days, field water duty assuming 40% losses during irrigation and amount of added water to irrigate one hectare. Ex4-3: Using Blaney-Criddle formula, calculate the irrigation interval through specific interval of plant growth according to the following data: . Mean air temperature 25 C percentage of day light hour through the month 8.4% Crop…
