## Problem 1010 and Problem 1011 | Investigation of timber reinforced by two steel channels

**Problem 1010**

A pair of C250 × 30 steel channels are securely bolted to wood beam 200 mm by 254 mm, as shown in Fig. P-1010. From Table B-2 in Appendix B, the depth of the channel is also 254 mm.) If bending occurs about the axis 1-1, determine the safe resisting moment if the allowable stresses σ* _{s}* = 120 MPa and σ

*= 8 MPa. Assume*

_{w}*n*= 20.

**Problem 1011**

In Problem 1010, determine the safe resisting moment if bending occurs about axis 2-2.
