17.(8 pts)The figure shows three forces of the same magnitude applied to a particle at the origin, withF1acting into the paper. With respect to the point P, rank the forces according to the magnitude ofthe torques produced, greatest first.A)F1= F2= F3B)F1= F2> F3C)F2> F3> F1D)F3=F2> F1E)F1> F2=F318.(8 pts)In the figure, a solid ball rolls smoothly down, starting at rest at H = 6 m and leaves thehorizontal ledge at height h = 2 m. How far in m from that ledge does it land?This study resource wasshared via CourseHero.com
Problem #1(28 pts,you must show your work): As shown in the figure, a uniform beam of lengthLsupported at angleθby a horizontal cable and a wall hinge. The tension in the cable isT. In terms ofθ,g,T,and numerical constants, as needed,A)(5 pts) draw forces acting on the beamB)(6 pts) find the gravitational force on the beam in unit-vector notation.C)(8 pts) find the force on the beam from the hinge in unit-vector notation.D)(9 pts)Then, the cable is cut and the beam is no longer in equilibrium.Find the magnitude anddirection of the initialangular accelerationof the beam about the hinge?This study resource wasshared via CourseHero.comisL,
Problem #2(28 pts,you must show your work): The figure gives the position (in cm) as a function oftime of a block attached to a spring with spring constantk= 5.0 x 103N/m. The maximum displacementfrom equilibrium is 7 cm, and the period of oscillation ists= 10 ms (millisecond).A)(5 pts) What is the mass of the block?B)(5 pts) What is the phase constant?C)(5 pts) What is the maximum elastic potential energy?D)(7 pts) What isthe maximum speed of the block?E)(6 pts) What is the spring force (magnitude and direction) acting on the block att= 0.0 s?This study resource wasshared via CourseHero.comPowered by TCPDF ()
