A force is successively applied at the end of a rod, perpendicular to it, as shown in the picture below (i.e., the force is pointing out of the page/screen). As a result, the rod is rotating ardand an axis passing through the other end and through the center, respectively, and has the same angular acceleration in both scenarios. Calculate the ratio F/F. F1 F2

. At the instant shown, end 4 of the rod has the velocity and acceleration shown. Determine the angular acceleration of the rod and the acceleration of end B of the rod. 4 m aA = 5 m/s² VA = 6 m/s 5 m B

The Subparts to be solved D & E. The angular position of a rod varies as 23.7t2 radians from time t = 0. The rod has two beads on it as shown in the following figure, one at r1 = 15 cm from the rotation axis and the other at r2 = 42 cm from the rotation axis. (Note: figure may not be drawn to scale.)   (a) What is the instantaneous angular velocity (in rad/s) of the rod at t = 7 s? (Indicate the direction with the sign of your answer. Round your answer to at least one decimal place.) rad/s (b) What is the angular acceleration (in rad/s2) of the rod at t = 7 s? (Indicate the direction with the sign of your answer.) rad/s2 (c) What are the tangential speeds of the beads (in m/s) at t = 7 s? vt, 1 = m/s vt, 2 = m/s (d) What are the tangential accelerations of the beads at t = 7 s? (Enter the magnitudes in m/s2.) at, 1 = m/s2 at, 2 = m/s2 (e) What are the centripetal accelerations of the beads at t = 7 s? (Enter the magnitudes in m/s2.) ac, 1 = m/s2 ac, 2 =…

Up Left Right Down A spinning disk is rotating at a rate of 4 rad/s in the counterclockwise direction as shown in the figure. If the disk is speeding up at a rate of 4 rad/s2, what is the direction of the angular acceleration vector? right down re 1 left hen up

In the image you see a sphere rolling down an inclined plane. Rolling without slipping. Is the weight (mg) producing any torque? Select the correct answer. mg O No O Yes 1P

Imagine that you could see a wheel spinning while speeding up, so you know that the angular velocity is (answer choice 1) , and the angular acceleration is (answer choice 2).  But if instead the wheel is spinning counter clockwise and slowing down, so you know that the angular velocity is (answer choice 3) , and the angular acceleration is (answer choice 4).  answer choices:  out of page (positive) or into page (negative)

For each question, use degrees NOT radians. Healthcare professionals, when measuring range of motion (ROM) and isokinetic strength, use degrees - so this assignment will use answers in degrees as well. A person is laying on their stomach doing a hamstring curl.  They go from fully extended (0o) to 130o of flexion.  What is their angular displacement if the person is on their stomach with their head facing left (feet pointing right)?

A 1.0 kg ball and a 2.0 kg ball are connected by a 1.1-m-long rigid, massless rod. The rod is rotating cw about its center of mass at 20 rpm. What torque will bring the balls to a halt in 5.6 s? Express your answer in newton-meters to two significant figures. ΠΑΣΦ T = ? N.m

Problem 1: A small rubber wheel is used to drive a large pottery wheel. The two wheels are mounted so that their circular edges touch. The small wheel has a radius of 6.5 cm and accelerates at the rate of 7.5 rad/s2 , and it is in contact with the pottery wheel (radius 24.0 cm ) without slipping. Part A Calculate the angular acceleration of the pottery wheel.   Part B Calculate the time it takes the pottery wheel to reach its required speed of 70 rpm .
