    Dynamics of a Suspended Mass on a Grooved Drum

    θHi BvU, thanks for the input. The question was handed in a tutorial on work done from uni with the answer given as 3.01m/s and I have since found this question in a Meriam textbook with the same answer but no worked example or one that is anything like it to draw from. I included the Mθ as I...

    Dynamics of a Suspended Mass on a Grooved Drum

    m(block)=8kg g=9.81m/s^2 r1=0.2m r2=0.3m k=0.21m m(drum)-12kg Torque(tf)=3Nm u=0.3 m/s I=mk^2 was used to calculate I of the drum Theta was calculated from = s/r

    Dynamics of a Suspended Mass on a Grooved Drum

    Hi BvU, I was using the theory that, T1 + ∑U1-2 = T2 Hence the 3Nm frictional torque was placed as a minus from the mgh on the left hand side. The frictional torque is stated as constant in the question hence I understand that it has to included as part the energy equation. I did this problem...

    Dynamics of a Suspended Mass on a Grooved Drum

    Dear All, would really appreciate some help with the following question - am struggling with dynamics at the minute! 1. Homework Statement An 8kg mass is suspended from a grooved drum at radius r1=200mm and with a speed of 0.3m/s it drops 1.5m. The outer radius of the drum is r2=300mm. Assume...
