【已刪除】1. Consider a particle of mass m constrained to move on the surface of a sphere of radius R subject to an applied
Here, we use the spherical coordinate systems
with the center of the sphere as the origin. Write down the equations of motion along the 0-direction and the direction, respectively. [20%]
【已刪除】2. The equation of motion of a damped oscillator can be expressed as
.
【已刪除】3.
【已刪除】4. Consider the double pulley system shown below. Assume the pulleys are massless and both strings across the pulleys are of fixed length i + ttR, where R is the radius of the pulleys. Use the method of Lagrange undetermined multiplier to find the tensions in both strings.
