Chapter 15, Problem 112P

The helical path is wound around the circular cylinder with radiusR . The step h= 2*pi*R. The object A is sliding through the path guide under gravity (acting in the negative zdirection). There is no air resistance 1)Draw the force diagrams in (theta ,Z ) plane (tangent to the cylinder) and in( r,theta ) plane. 2) If the initial speed is 0, find the speed after 3 full circles. Given: R, g, m, u.[Hint: Use the work-energy principle.]

take m and k as ; m= 0.18 kg,   k = 128 N/m

The sports car, having a mass of 1700 kg, travels horizontally along a 20° banked track which is circular and has a radius of curvature of p = 100 m. Determine the normal force of the car in Newton.

The box with a weight of 6 lb slides down the smooth surface that has a circular portion AB. If the speed of the box is 8 ft/sec at A, calculate the magnitude of the normal force acting on the box at C. Present your answer in lb using 3 significant figures. The following relations may be useful: sin(A + B)=sin A c ·cos B±cos A-sin B cos(A + B) = cos A cos B sin A-sin B 45° B 0=30° 20 ft 8 ft/s A 45°

M = A frisbee is thrown such that its final angular velocity is w = 9 after being in flight for t = 2 s. As it rad S flies, the wind applies a constant moment, causing the frisbee to rotate faster. If the frisbee was initially at rest, determine the moment of the wind and the work done by said moment. Assume the frisbee can be modelled as a disk with mass m = = 0.15 kg and that it rotates about its center of gravity G. The frisbee has a radius of r = 0.12 m. UM = N.m r J G M

The spool, which has a mass of 2 kg. slides along the smooth horizontal spiral rod, r = (0.400) m, where is in radians. as shown in (Figure 1).

The tractor is used to lift the 170-kg load B with the 24-m-long rope, boom, and pulley system. The tractor travels to the right with an acceleration of 4 m/s² and has a velocity of 5 m/s at the instant SA = 5 m. When SA = 0, SB = 0.
