The hand brake for a bicycle is shown. Portions DE and FG are free to rotate on bolt A which is screwed into the frame BC of the bicycle. The brake is actuated by a shielded cable where T1 is applied to point E and T2 is applied to point G. A spring having 40 N compressive force is placed between points E and G so that the brake stays open when it is not being used. Assume the change in the spring's force is negligible when the brake is actuated to produce the F = 100 N forces at points D and F. Determine the necessary cable forces T1 in N.
Question 2:
The ideal spring of constant k-2.6 kN/m is attached to the disk at point A and the end fitting at point
B, as shown. The spring is unstretched when OA and Oв are both zero. If the disk is rotated 15° clockwise
and the end fitting is rotated 30°counterclockwise, determine the vector expression for the spring force
F.
Determine distance C so that the moment the spring force makes about the Z axis is equal to 10.82

where e = 28" to the position where 0 = 63°? The spring has a stiffness of k = 157 N/m and is stretched
by 0.21 m when e =0°. The spring is connected to a fixed wall, as well as the endpoint of the rod, as
shown. The rod can rotate freely about the fixed pin support at O and AO remains horizontal during
motion. Take 40= 1.77 m, which is also the length of the rod. Choose the correct answer.

- Each arm of a Proell governor is 240 mm long and each 240 h = 190 rotating ball has a mass of 3 kg. The central load acting on the sleeve is 30 kg. The pivots of all the arms are 30 mm from the axis of rotation. The vertical height of the T. Tcos e governor is 190 mm.

The belt that surrounds pulley A tries to stop it unsuccessfully, resulting in pulley A rotating at a constant speed while the belt is fixed. The belt in turn passes through an idle pulley B (frictionless pulley) and pulls a block of mass m2 that is attached to the wall by a spring. If it is considered that the spring has already been stretched by the effect of the tension of the band and that said block is in a condition of imminent movement in the direction to the left, determine: a) The magnitude of the torque M applied to pulley A in the counterclockwise direction. b) The elongation of the spring for the exposed condition.

The light rope that connects the two blocks does not slip over the surface of the pulley (radius 0.080 m) because the pulley rotates on a frictionless axle. The horizontal surface on which block A (mass 2.50 kg) moves is frictionless. The system is released from rest, and block B (mass 5.00 kg) moves downward 1.80 m in 2.00 s.

- The mechanism shown consists of a crank (bar AB), a connecting rod (bar BC) and the piston C that slides on the smooth surface (without friction). The combustion of gasoline produces a force P on the piston and this is kept in equilibrium with the moment M applied in A. The length of the crank is 116 mm, the length of the connecting rod is 183 mm, the force P is 710 N and the angle theta is 0.56 radians. Determine the value of M in Nm.arrow_forwardA.The bar of negligible weight is supported by two springs, each having a stiffness k = 98 N/m. If the springs are originally unstretched, and the force is vertical as shown, determine the angle the bar makes with the horizontal, when the 31-N force is applied to the bar. B.Determine the stiffness k of each spring so that the 32-N force causes the bar to tip = 13.6° when the force is applied. Originally the bar is horizontal and the springs are unstretched. Neglect the weight of the bar.arrow_forwardTorsional springs provide a simple propulsion mechanism for toy cars. When the rear wheels are rotated asif the car were moving backward, they cause a torsional spring (with one end attached to the axle and the other to thebody of the car) to wind up and store energy. Therefore, a simple way to charge the spring is to place the car onto asurface and to pull it backward, making sure that the wheels roll without slipping. Note that the torsional spring canonly be wound by pulling the car backward; that is, the forward motion of the car unwinds the spring.Let the weight of the car (body and wheels) be W = 5 oz, the weight of each of the wheels be Ww= 0.15 oz, and theradius of the wheels be r = 0.25 in., where the wheels roll without slip and can be treated as uniform disks. Neglectingfriction internal to the car and letting the car’s torsional spring be linear with constant kt= 0.0002 ft-lb/rad, determinethe maximum speed achieved by the car if it is released from rest after pulling it…arrow_forward
