Rule 48.1 & Table 5

48.1 Wood

Values used for moduli of rupture for wood in bending, in conjunction with safety factors given in Rule 44, shall not exceed those shown in Table 5.

Table 5 Wood strengths
Species	Modulus of rupture in bending
Species	Sawed rectangular poles, crossarm, etc. (a)	Round Poles
Cedar, western red	4,700 lbs. Per sq in	5,600 lbs. Per sq in
Douglas fir, dense	6,300 lbs. Per sq in	6,800 (b) lbs. Per sq in
Douglas fir, not dense	5,800 lbs. Per sq in	6,800 (b) lbs. Per sq in
Fir, white or red, local	4,700 lbs. Per sq in	5,600 lbs. Per sq in
Pine, southern yellow, dense	6,300 lbs. Per sq in	6,800 (b) lbs. Per sq in
Pine, southern yellow, not dense	5,800 lbs. Per sq in	6,800 (b) lbs. Per sq in
Redwood, virgin	5,300 lbs. Per sq in	6,200 lbs. Per sq in
Redwood, second growth	3,900 lbs. Per sq in	4,600 lbs. Per sq in

(a) Figures given are for select structural grade of material under short time loading with the neutral plane parallel to a side. Multiply the values shown by 1.4 where the neutral plane is on the diagonal of a square. Multiply the given values by 0.55 where the loading being considered is a long time loading (continuous load for one year or more).

(b) Where poles meet specifications of American Standards Association, 05.6-1941 for Douglas Fir Poles (creosoted) and 05.4-1941 for southern Pine Poles (creosoted), this value may be increased to not more than 7,400 lbs. Per square inch.
