L cos 0<

Rrr = 0.55 (I 1 1O){7.IO)(I) (0.997) = 2350 kN

1.84

RYA = 0.55 (1110)(7.29)(_1_) (0.997) = 2373 kN

1.87

R X = N (O.55)(MBL) cos f3 cos e

Af, variation in L, cos (J and cos e is less than 2070 the simpler approximate formula may be
used giving:

RXF = 2 (0.55)(1110)(0.988)(0.999) = 1205 kN

R){A = 2 (0.55)(J 110)(0.984)(0.998) = J200 kN
