The uniform 10-kg ladder in Figure 02 rests against the smooth wall at B. and the end A rests on the rough horizontal plane for which the coefficient of static friction is us = 0.3. Given that reactions at A and B are NA = 98.1 N, FA = 29.43N and NB = 29.4 N. Determine the angle of inclination 8 of the ladder and the normal reaction at B if the ladder is on the verge of slipping. B 10(9.81) N (4 m) sinė ΔΑ A N (2 m) cose (2m) cose 16.7° 32.8° 45.0° 59.0°
