A horizontal beam is fixed at both ends (obostrano uklještenje). Length = 8 m. A point load of 1000 N acts at 3 m from left end. Determine reactions at both ends. (Note: This is statically indeterminate in real structures, but some high school problems assume symmetry or give extra conditions – treat as exercise in moment equilibrium.)
. Kod uklještenja obavezno uračunajte reaktivni moment koji sprečava rotaciju grede. statika zadaci za srednju skolu fixed
Lena had mastered the simple problems: a book on a table, a sign hanging from two ropes. But this? This was different. This was the statics of resistance . A horizontal beam is fixed at both ends
