Etymology

From Middle English beem, from Old English bēam (“tree, cross, gallows, column, pillar, wood, beam, splint, post, stock, rafter, piece of wood”), from Proto-West Germanic *baum, from Proto-Germanic *baumaz (“tree, beam, balk”), from Proto-Indo-European *bʰew- (“to grow, swell”). Cognate with North Frisian Boom, buum (“tree”), Saterland Frisian Boom (“tree”), West Frisian beam (“tree”), Cimbrian pome, póom, puam (“tree”), Dutch boom (“tree”), German Low German Boom (“tree”), German Baum (“tree”), Luxembourgish Bam (“tree”), Mòcheno pa'm (“tree”), Vilamovian baojm (“tree”), Yiddish בוים (boym, “tree”), Danish, Norwegian Bokmål, Norwegian Nynorsk, and Swedish bom (“beam”), Icelandic baðmur (“tree”), Gothic 𐌱𐌰𐌲𐌼𐍃 (bagms, “tree”), Albanian bimë (“a plant”). Doublet of boom. The original English meaning of beam ("tree") is preserved in some compound words such as quickbeam. The verb is from Middle English bemen, from Old English bēamian (“to shine, to cast forth rays or beams of light”), from the noun.

And a letter vnto Asaph the keeper of the kings forrest, that he may giue me timber to make beames for the gates of the palace which appertained to the house, and for the wall of the Citie, and for the house that I shall enter into: And the king granted me, according to the good hand of my God vpon me.1611, The Holy Bible, […] (King James Version), London: […] Robert Barker, […], →OCLC, Nehemiah 2:8:

One of the principal horizontal structural members, usually of steel, timber, or concrete, of a building.

The brasswork here, how rich it is in beams, / And how, besides, it makes the whole house sound.1614–1615, Homer, “(please specify the book number)”, in Geo[rge] Chapman, transl., Homer’s Odysses.

Lucie opened the door: and what do you think there was inside the hill?—a nice clean kitchen with a flagged floor and wooden beams—just like any other farm kitchen.1905, Beatrix Potter, The Tale of Mrs. Tiggy-Winkle:

Nautical, Transport One of the transverse members of a ship's frame on which the decks are laid, and acting as part of the support for keeping the sides of the vessel in shape — supported at the sides by knees in wooden ships and by stringers in steel ones; cf. abeam, beam-ends.

Capt. King, from Demarara, was invaded by the gale on the evening of the 6th, in lat. 21° 51', and his vessel was thrown on her beam ends. He was forced to cut away her main-mast. Lost a man, who was washed overboard. . . . Capt. Mood, on a voyage from Alexandria (Virginia), to St. Mary's (Georgia), was, on the night of the 7th, in the Gulf Stream, to the eastward of Charlston: the wind there was east-north-east, and so hard as to throw his vessel on her beam ends. She lay several hours in this situation. Several of his crew were washed overboard.1805 Alexander Tilloch. Account of a terrible Hurricane in the West Indies 1804. Philosophical Magazine. Vol. XXI. P. 14
1808 Richard Hall Gower. On the Theory and Practice of Seamanship. It often happens that by a sudden squall of wind a vessel is thrown over upon her beam ends, without a prospect of recovering her erect while she remains upon the same tack, therefore attempts are made to veer her; but as the rudder lies along the surface of the water it becomes useless, and as the sails are either blown from the yards, or become unmanageable, recourse is had to cutting away the main-mast and mizen-mast, that the ship may veer under the fore-mast:-a most desperate expedient, particularly if the ship is far distant from port!

Nautical, Transport The maximum width of a vessel (note that a vessel with a beam of 15 foot can also be said to be 15 foot abeam).

This ship has more beam than that one.
Being only 280 ft. long, with a beam of 66 ft, their speed is moderate, and for a long time difficulty was experienced in steering them.1892, Sydney Marow Eardley-Wilmot, The Development of Navies During the Last Half-Century, Chapter 7:

Nautical, Transport The direction across a vessel, perpendicular to fore-and-aft.

As the vessel passes a landmark, the landmark is said to be abeam. Once the vessel has passed the landmark, it falls abaft the beam, then it gradually falls astern.

Nautical, Transport The straight part or shank of an anchor.

Engineering, Mechanical, Mechanical engineering, Natural sciences, Physical sciences The crossbar of a mechanical balance, from the ends of which the scales are suspended.

Soon after this be subdued the Pisidians who made head against him, and conquered the Phrygians, at whose chief city Gordium (which is said to have been the seat of the ancient Midas) he saw the famous chariot fastened with cords made of the bark of the Cornel-Tree, and was informed that the inhabitants had a constant tradition, that the empire of the world was reserved for him who should untie the knot. Most are of opinion, that Alexander finding that he could not untie it, because the ends of it were secretly folded up within it, cut it asunder with his sword, so that several ends appeared. But Aristobulus tells us that he very easily undid it, by only pulling the pin out of the beam which fastened the yoke to it, and afterwards drawing out the yoke itself.a 1700, André Dacier, John Dryden, “Life of Alexander”, in Plutarch's Lives, translation of original by Plutarch:
