A four-bar mechanism is working on horizontal plane. The second link length is 0,4 m and makes an angle of 0=25 degrees with the vertical line as shown in figure. Find the torque (T) in Nm must be applied to link 2 to keep the mechanism in equilibrium against a F=132 N force acting at E on the link 3 downward (along negative y- axis) direction. Allowable tolerance for your answer of this question is relatively 3 percent. So, work precisely and clear while solving it. Do not enter any UNIT. (If the direction of the torque is CCW, just enter the value of it without any sign. If it has CW direction, enter "-" sign "negative sign" before the value such as "- 12,12".)

3 In a compound helical spring, the inner spring is arranged within and concentric with outer one but is 10 min shorter. The outer spring has 10 coils of mean dianmeter 30 min and wire dia 3 mm. Find stiffness of inner spring if an axial load of 100N causes outer one to compress by 20 mm. If the radial clearance between the springs is 2 mm, find wire diameter of inner spring which has 8 coild. G 80 kN/mm.
