$($Problem $1,$ Continuod$)$

a$.$ Using Reduced Structure $1,$ determine the deflection at B $(B)$ due to the $4$

kip applied load.

Notes:

$(1)$ the given deflection equation assumes posisve defections is up

b$.$ Using Reduced Structure $2,$ determine the flexibility coefficient fen.

Notes:

$(1)$ fee $=$ deflection at $B$ due to a unit load eppled at B

$(2)$ The unit load is applied down to malch the given deflection equation

c$.$ In the real structure the deflection at B is zero. Use the compatibility

equation below to determine $B_y.$

$By{f}_0+A_0=0$

Notes:

$(1)$ Be sure to heep the correct sions from parts a and b$.$

$(2)$ The sign of $B,$ will be relative to the drection of the unit force in Reduced Structure $2.$

$($meaning negative is up$)$

d$.$ Now that $B$ y is known, use statics to find the reactions at A $.$
