Answer 1

PART A:

$a_{G}=0.272m/s^{2}$

PART B:

$N_{A}=95837.77N$

PART C:

NB — 94326.11N

The detailed solution is given below:

Giveno ma 2T=6KN L + X T G RT maGo 2.5m 231 127 B A W n = 29 My I T'=1.9 KN = 210g #PARTA: → LES mx AGx T+2T= mxabe (1900N )+ (6000N) (29x10²kg) x aard 943<6m- 2NB → A Que = 10.272m 152 Ingo Frebody diagram #PARTB and PARTC > {fy = magy = 0 > Natal NATONB (29x103 trios kg) x 1x (7.81m62) = 284490N NA RNB mg or EMG=0 () -T'x(2.5–1.2) – 27x(2.3–1-2) – 2 Ng x3 + NAx6 = 0 -(1900N) x(1-3)- (6000N) x (1.1) – 6N8 +6 NA = 0 6N4-6Ng = 9070 N NA 9070 +6NB or 6

put value of NA in On we get 19070 +6 NB + 2NB +2NB = 284490 6 > Ng = 194326.11N Put above value in we → NA = 195837.77 M get
