I-beam

I like how Macchi makes an I-beam do the one thing it is absolutely meant not to do: bend.

Wyman collapsed into the bay of the I-beam as if he'd been kicked in the stomach.

This is essentially a steel I-beam (A) which grips the logs so that they will not slip.

He stood at last, quivering, leaning against a gigantic I-beam that supported a heavy-casting freightway.

The balance is attached to an upright I-beam which is anchored to the floor and ceiling of the calorimeter laboratory.

I-beam was not loaded to its full capacity, its deflection caused an outward flexure of 3/4 in.
