The 0.6 m uniform slender bar has a mass of 5 kg. Two springs 1 and 2 having stiffness k, = 80 N/m and k₂= 45 N/m respectively are attached at end B of the slender bar. A 20 kg mass is suspended through a rope of negligible weight at the other end as shown. If a counter-clockwise moment M = 10 N.m is applied on the bar when it is at rest in the horizontal position, determine the angular velocity (₂) of the slender bar when it has rotated 30° couterclockwise. Note: Both springs always remain vertical because of the roller supports shown and are unstretched when the bar is horizontal.

Question
Transcribed Image Text:The 0.6 m uniform slender bar has a mass of 5 kg. Two springs 1 and 2 having
stiffness k, = 80 N/m and k₂= 45 N/m respectively are attached at end B of the
slender bar. A 20 kg mass is suspended through a rope of negligible weight at the
other end as shown. If a counter-clockwise moment M = 10 N. m is applied on the
bar when it is at rest in the horizontal position, determine the angular velocity (₂)
of the slender bar when it has rotated 30° couterclockwise. Note: Both springs
always remain vertical because of the roller supports shown and are unstretched
when the bar is horizontal.
