# increase in moment

## Problem 1004 | Increase in moment capacity due to aluminum plate reinforcement

**Problem 1004**

Repeat Problem 1002 assuming that the reinforcement consists of aluminum plates for which the allowable stress is 80 MPa. Use *n* = 5.

## Problem 1002 | Increase in moment capacity due to steel plate reinforcement

**Problem 1002**

A timber beam is reinforced with steel plates rigidly attached at the top and bottom as shown in Fig. P-1002. By what amount is moment increased by the reinforcement if n = 15 and the allowable stresses in the wood and steel are 8 MPa and 120 MPa, respectively?
