The uniform 4 meter boom has a mass of 60 kg and is pivoted to the back of the truck at A and secured by a cable at C. Calculate the magnitude of the total force supported by the connection at A if the truck starts from rest with an acceleration of 5 m/s^2. Answer is A=1192 N Distance from A to B=4 m at 120 degree angle relative to the line AC Distance from A to C= 2m
