B=10 ; 270⁰
C=15 ; 210⁰
D=12,5 ; 315⁰
E= 7,5 ; 75⁰
F = 10 ; 215⁰
G= 15 ; 100⁰
Write and draw the following grashof's criterion and kind of grashof's four-bar mechanism such as;
1. Crank-rocker mechanism;
2. Drag link mechanism;
3. Double rocker mechanism;
4. Crossover-position or charge-point mechanism;
5 Triple rocker mechanism (non-grashof).
Use technical Pen for the following:
0.2(light -for linkages and hand writing),
0.4(medium - for joints),
0.6(heavy - for fixed link or frames)
use 2-4-4 template, all caps, italicized.

- The number of degrees of freedom of the linkage shown in the figure.arrow_forwardFigure Q2-2 shows a schematic of a retractable landing gear of aircraft. The retraction mechanism is a 4 bar linkage (O1ABO2), which is actuated by a hydraulic cylinder and piston, D, pivoted at E with a joint at C to link O,A. Hydraulic cylinder & piston D Joint for landing gear wheel Figure Q2-2 Use the Gruebler's equation of DoF (Degrees of Freedom) of a linkage mechanism to assess if the landing gear produces the required retraction motion. 0,02 may be considered as the ground link. i) Hint: The joint of the wheel is not part of the linkage mechanism. The number of DoF may be used to check if it is a linkage with certain motions or a fixed structure. ii) The dimensions of the 4 bar linkage (O1ABO2) are measured as O102 = 800 mm, O1A = 780 mm, AB = 200 mm and O2B = 400 mm. Use Grashof condition to determine the specific type of this linkage. You may find the Gruebler's equation useful: M = 3(L – 1) – 2J where, M is degree of freedom (DoF) L is number of links J is number of jointsarrow_forwardThe number of degrees of freedom in the 3 link mechanism shown below is given byarrow_forward
