Circular Motion Due to Tension A carnival ride consists of a mock rocket rotating around a central shaft. A view of this ride as seen from above is shown below. The rocket is connected to the central shaft by a rigid beam, which is parallel with the ground. A conservative high estimate of the total mass of the rocket+passengers is 750 kg. The bolt connecting the beam to the central shaft breaks when the tension in the beam exceeds 4830 N. What is the maximum number of revolutions per minute (rpm) that the rocket can have if the ride is designed by the engineers to have a 3:1 safety factor? A 3:1 safety factor means that the tension in the beam cannot exceed one third of its breaking strength (i.e. one third of 4830 N). (answer: 5.1 rpm) r = 7.5m

I am pretty sure that this can be solved by adding 57 to mg cos(theta) but when I enter -59.196 into the problem it says that it is incorrect.
A spherical glass bead of mass M and radius R is releasedfrom rest at the top of an inclined track (angle  with thehorizontal) that ends in a curved section of radius r. Theglass bead rolls down the incline without slipping; there isfriction between the ramp and the glass bead. The momentof inertia of the glass bead is I = 2/5 MR2 Draw a force diagram for the glass bead on the ramp.Label all forces clearly Determine the linear acceleration of the marble when it is rolling down the incline. Your answer will be interms of theta and g . Determine the speed of the marble at the lowest point of the incline in terms of H and g.

Question 2 please
Partially correct answer iconYour answer is partially correct. In the figure, block 1 has mass m1 = 470 g, block 2 has mass m2 = 600 g, and the pulley is on a frictionless horizontal axle and has radius R = 5.0 cm. When released from rest, block 2 falls 77 cm in 4.9 s without the cord slipping on the pulley. (a) What is the magnitude of the acceleration of the blocks? What are (b) tension T2 (the tension force on the block 2) and (c) tension T1 (the tension force on the block 1)? (d) What is the magnitude of the pulley’s angular acceleration? (e) What is its rotational inertia? Caution: Try to avoid rounding off answers along the way to the solution. Use g = 9.81 m/s2. I am having a problem with part E I got 0.0366 as wrong answer
