The following data apply to a four-bar linkage similar to the one illustrated in Fig. 3: RA02 =120 mm, R0402 = 300 mm, RBA = 320 mm, RB04 = 250 mm, RCA = 360 mm, 0c = 15°, RD04 = 0, 0D = 0°, RG202 = 0, RG3A = 200 mm, α = 8°, RG404=125 mm, ẞ =0°, m2 = 0.5 kg, m3 = 4 kg, m4 =1.5 kg, IG2 = 0.005 N m s², IG3 0.011 N m s², IG4=0.0023 N m s². A kinematic analysis at 02 = 90° and 2 = 32 rad/s² ccw with α2 = 0 and gave 03 = 23.9°. 04 = 91.7º, α3 = 221 rad/s² ccw, α4 =122 rad/s² ccw, AG3 =88.6 m/s² 255°, AG4 =32.6 m/s² 244°.

Problem 4 For the 6 bar Watt's mechanism shown below, the link lengths are as follows: O2A = 1, AB = 1.2, 0204 = 2, 04B = 2, 0406 = 1.9, 06D = 2.4, CD = 1. Also O4C = 04B = BC. The input angle is 02. For 02 = 45 degrees, find the positions of the moving pivots A, B, C, and D in the global coordinate system YO2X. 0406 makes an angle of -30 degrees with the horizontal axis.

If the link lengths of a four-bar linkage are L1 = 1 mm, L2 = 3 mm, L3 = 4 mm,and L4 = 5 mm and link 1 is fixed, what type of four-bar linkage is it? Also, is the linkage a Grashof type 1 or 2 linkage? Answer the same questions if L1 = 2 mm.

i need to solve part b pls quickk very urgent part (a) is solved

I want to explain where the numbers 6.2772 and -1.274 come from(are marked in red) just calculation for the two nb

Example Problem 4-1, (page 141). [Ref.1]: The shaft shown in Figure 4-7 is supported by two bearings and carries two V-belt sheaves. The tensions in the belts exert horizontal forces on the shaft, tending to bend it in the X-Z plane. Sheave B exerts a clockwise torque on the shaft when viewed toward the origin of the coordinate system along the X-axis. Sheave C exerts an equal but opposite torque on the shaft. For the loading condition shown, determine the principal stresses and the maximum shear stress on element K on the front surface of the shaft (on the positive Z-side) just to the right of sheave B, Follow the general procedure for analyzing combined stresses given in this section.
