Question

A 10 -ft bar of l-beam weighs 201 lb . What is the weight of a $$ 11-\mathrm{ft} $$ length? The weight of a 11 -ft bar is $$ \square \mathrm{lb} $$. (Simplify your answer.)

UpStudy AI · Accepted Answer

To find the weight of an 11‑ft L-beam, we can assume that the weight is directly proportional to its length.

1. **Determine the weight per foot:**
   $$
   \text{Weight per foot} = \frac{201 \, \text{lb}}{10 \, \text{ft}} = 20.1 \, \text{lb/ft}
   $$

2. **Calculate the weight of an 11‑ft bar:**
   $$
   \text{Weight of 11‑ft bar} = 20.1 \, \text{lb/ft} \times 11 \, \text{ft} = 221.1 \, \text{lb}
   $$

Therefore, the weight of an 11‑ft L-beam is:

$$
221.1 \, \text{lb}
$$
The weight of an 11-ft bar is 221.1 lb.
