At time ? = 0 link OA of the mechanism shown below has an initial angular velocity of ??? = 9? ???/? and is at a position of ? = −30? . Suddenly, a brake is applied which provides a time-dependent deceleration of link OA of ??? = (−1 − ?)? ???/?2 . Use kinematic relationships to find expressions for the angular velocity of link OA (???(?)) as well as the angular position of point A (?(?)) on the link...
PROBLEM: The rod OA in Fig. 12–33a rotates in the horizontal plane such that 0 = (rº) rad. At the same time, the collar B is sliding outward along OA so that r = (1001) mm. If in both cases t is in seconds, determine the velocity and acceleration of the collar when 1 = 1 s. SOLUTION Coordinate System. Since time-parametric equations of the path are given, it is not necessary to relate r to 0. Velocity and Acceleration....

please help! data is provided and be detailed so i can understand Problem I (40pts) Evans et al. (A-5) examined the effect of velocity on ground reaction forces (GRF) in dogs with lameness from a torn cranial cruciate ligament. The dogs were walked and trotted over a force platform and the GRF recorded (in newtons) during the stance phase. The table contains 22 measurements (see problem 1.xlsx) of force expressed as the mean of five force measurements per dog when...

2. Consider a mass m moving in R3 without friction. It is fasten tightly at one end of a string with length 1 and can swing in any direction. In fact, it moves on a sphere, a subspace of R3 1 0 φ g 2.1 Use the spherical coordinates (1,0,) to derive the Lagrangian L(0,0,0,0) = T-U, namely the difference of kinetic energy T and potential energy U. (Note r = 1 is fixed.) 2.2 Calculate the Euler-Lagrange equations, namely...
