Determine the maximum allowable spacing of joist used with nominal 1-inch lumber decking if the design load is 200 psf. Assume the decking is continuous over 3 or more spans and is hemlock-fir. Limit deflection to I/360. Assume 1x12 Do not apply 7 day load duration factor or reduction factor for wet conditions.

Determine the maximum allowable span of nominal 2x4 wall forms studs carrying a design load of 1000 psf. Stud spacing is 16” on center. Use the allowable stresses for Douglas Fir from Table 13-8 and 7 day load duration. Assume that studs are continuous over 3 or more spans. Limit deflection to l/360 of span length. Based on the maximum allowable span, check for crushing of studs on double 2x4 wales. Conditions are dry.

A lumber floor joist is designed from Douglas Fir-Larch number 1 and better. The joist is simply supported over a span of 12' and is part of a floor system that includes repetitive joist framing at 16" o.c and a plywood subfloor. Assume dry and normal temperature service conditions. The joist carries 25 plf of dead load and 55 plf of live load. Size the joist.

Determine the Maximum Likelihood Estimator for; 1. λ for the Poisson distribution. 2. θ for the Exponential distribution. Caveat: These are examples of distributions for which the MLE can be found analytically in terms of the data x1, . . . , xn and so no advanced computational methods are required and also in each assume a random sample of size n, x1, x2, . . . , xn
