1 12 Ui A A H A 1do Ke Steel Beam Is Connected To A Ceiling Fixture Via Two Pil

(1)12)UIAAH+A 1DO KE steel beam is connected to a ceiling fixture via two pill joints at A and B .The beam is initially in a horizontal position when the pill joint at & fails , and the*beam begins to swing about the remaining pill joint at A. Assuming the beam callbe modelled as a thin rod , with length [ = 2171 :i .Determine the initial magnitude of reaction force acting at pill joint A atthe instance where pill joint & fails at $ = 0′ ( 10 Marks )11 .According to the 11 – taxes displayed on the figure above , determine*expressions for :a . The reaction force at joint A in the normal ( 1 ) direction as afunction of $ ( 5 Marks )6 . The reaction force at joint A in the tangential ( t ) direction as afunction of $ ( 5 Marks )
