A) String one has 20 g on its mass hanger and is located at an angular position of q1= 0°. String two 40 g of mass on the mass hanger and is located at an angular position of q2= 180°. Is there a third string that can be added such that it brings the system into equilibrium if the angular position of this third string is not 0°or 180°? This system refers to the balancing of a force table. Support your answer with a detailed explanation or mathematical analysis.
B) String one has a mass of 10 g on its mass hanger and so does string two. If string three has a mass of 30g on it, can this system be brought into equilibrium by placing the strings at just the right angular positions? This system refers to balancing a force table. Support your answer with a detailed explanation or mathematical analysis.

A laboratory on the concept of static equilibrium uses an apparatus called a force table. The force table consists of a round, level platform marked in degree increments about its circumference. In the center of the table sits a massless ring, to which three strings are tied. Each string is strung over a separate pulley clamped to the edge of the platform, and then tied to a freely-hanging mass, so that each string is under tension and the ring is...

A horizontal spring-mass system has a mass of 250 g and spring stiffiness of 4 N/m. If the mass is given an initial velocity of 0.1 m/s to the tight from a starting point 0.05 m to the left of the equilibrium point, give: 1) the equation of motion of the mass 2) the position of the mass at 0.5 s, t s and t-2 s 3) a graph of x() from t os tot 2 s,...

The entire system shows here rotates at constant angular rate w,
and m1 is almost about to slip up the incline. The pulley is
“ideal” and the string supporting m2 has a length of 3.0 meters.
Each mass rotates in a horizontal circle, but with different
r-values, one of which is given. Draw a clear force diagram for
each mass, write down the appropriate force equations, and solve
them to find the tension (T) in the string, the normal force...
