2W = T , where T is the tension in the rope connected to pulley r2 pulley.
T = W/2, balancing torques we have, T*r2 = P*r1

Fly Wheel: The fly wheel has a mass M , a radius R , and a moment of inertia I=1/2MR^2 . The fly wheel has a gear of radius Rg < R that is used to turn the wheel. Drive Chain: The drive chain connects the gear on the fly wheel to a motor. The gear, the black circle in the middle, rotates with the wheel and the chain is pulling on the gear without slipping in the...
1. A Ferris wheel at a carnival has a radius of 8 m and turns so that the speed of the riders is 11 m/s. (a) What is the magnitude of the centripetal acceleration of the riders? (b) What is the magnitude of the net force is required to produce this centripetal acceleration for a rider with a mass of 65 kg? 2.Two 325-kg masses (722 lb) are separated by a distance of 6 m. Using Newton's law of gravitation,...
plz? help sir .......... A transparent glass hemisphere with radius R and mass m has an index of refraction n. In the medium outside the hemisphere, the index of refraction is equal to one. A parallel beam of monochromatic laser light is incident uniformly and normally onto the central portion of its planar surface, as shown in Figure 3. The acceleration of gravity g is vertically downwards. The radius 8 of the circular cross-section of the laser beam is much...

A wheel-axle assembly is attached to a spring as shown in the figure below. The wheel-axel assembly has a mass of m=3 kg and a radius of gyration about the polar axis of kG=75mm. The spring has a stiffness of k=0.5 kN/m ( Note the units!). The system is released from rest with a spring extension of x1=0.2 m. Calculate the maximum angular velocity. Assume friction can be ignored. Provide your answers in rad/s.
A person holds two bricks together in one hand, pinching them as indicated by the arrows in the -figure to the left. As can be seen, the bricks have a tendency to swing apart at the bottom, contacting only at their top edges. We want to analyze the system to better understand its behavior and stability conditions (i.e. the bricks are not swinging around or falling out of the person's hand). This is done by analyzing a free body diagram...
3. A very thin circular hoop of mass m and radius r is made to roll, without slipping, down a ramp with an angle of inclination (with respect to the horizontal), as shown in the figure below. See Figure 3. Note: The moment of inertia of the thin circular hoop is given by: I houp = mra Consider a system consisting of a ladder with a painter climbing said ladder. The ladder has a length 1 = 5,00 meters and...

No c Consider the pulley and weight system shown in the figure. (Figure 2) The pulley has mass 14.0 kg, outer radius R -190 mm, inner radius Ri- 140...
(9%) Problem 3: A bicyclist notes that the pedal sprocket has a radius of rp = 9.5 cm while the wheel sprocket has a radius of rw = 6.5 cm. The two sprockets are connected by a chain which rotates without slipping. The bicycle wheel has a radius R = 64 cm. When pedaling the cyclist notes that the pedal rotates at one revolution every t= 1.4 s. When pedaling, the wheel sprocket and the wheel move at the same...
