The four particles in Figure.1 are connected by rigid rods of negligible mass. The origin is at the center of the rectangle. If the system rotates in the xy plane about the z axis with an angular speed of 6.00 rad/s, calculate (a) the moment of inertia of the system about the z axis and (b) the rotational kinetic energy of the system.
Find the net torque on the wheel in Figure. 2 about the axle through O if a = 10.0 cm and b = 25.0 cm.
A block–spring system oscillates with an amplitude of 3.50 cm. If the spring constant is 250 N/m and the mass of the block is 0.500 kg, determine (a) the mechanical energy of the system, (b) the maximum speed of the block, and (c) the maximum acceleration?
Consider the simplified single-piston engine in Figure.4. If the wheel rotates with constant angular speed, explain why the piston rod oscillates in simple harmonic motion.
The angular position of a pendulum is represented by the equation. θ = (0.320 rad)cos ω t , where θ is in radians and ω = 4.43 rad/s. Determine the period and length of the pendulum.
may ignore the mass of the wire when calculating the tension in it.)
