HOMEWORK PROBLEM 2 Given the driver crank length L1 = 100mm, coupler length L2 = 200 mm, and follower length 13 = 300 mm, and considering the transmission angle, find the range of values for the fixed link Lo if the linkage is to be a crank rocker. Make the design decision to limit the transmission angle to 45° 5° 135º.

#1. Design a crank rocker mechanism (four bar linkage) where the rocker length is between 3 inch and 3.5 inch with a swing angle of about 45 degree. Also the time ratio (Q) of the linkage is required to be between 1.5 and 1.75 (20 pts). Clearly show the lengths of the crank, coupler and fixed frame of your design (10 pts). Locate a coupler point about o.S inch above the mid-point of your coupler (5 pts). Draw the linkage...

HOMEWORK PROBLEM 1 The Grashof Criterion This problem concerns the classification of four-bar linkages. Link lengths: Lo, fixed link; Ly, driver crank; L2, coupler; L3, follower crank; L2 = 100 mm, 12 = 200 mm, 13 = 300 mm. Find the ranges of values for Lo, if the linkage can be classified as follows: a. Grashof mechanism b. Crank-rocker mechanism c. Drag link mechanism d. Double-rocker mechanism e. Change --point mechanism f. Triple-rocker mechanism

Please Solve and Give Detail. Thank you.
For a four-bar mechanism, the link lengths in inches and the value of the angle 02 are as follows: Link 1-5, Link 2-3, Link 3-8, Link 4-9, θ. = 45 degrees. Link l is the ground and link 2 is the driving link. (a) Is this a crank-rocker, double rocker, double crank or triple rocker mechanism? Justify your answer. [5 points] (b) Find the angles 0.04 and transmission angle when θ2 45 degrees...

The four-bar mechanism lies in a vertical plane and is
controlled by crank OA which rotates counterclockwise at a
steady rate of 55 rev/min. Determine the torque M which
must be applied to the crank at O when the crank angle
θ = 41°. The uniform coupler AB has a mass of 9.6
kg, and the masses of crank OA and the output arm
BC may be neglected.

Figure 8 (c) Figure 9 illustrates a four-bar linkage mechanism that is used to operate a washing system on a vegetable harvesting line. The mechanism consists of a crank OA which moves in a limited arc and an L-shaped connecting rod AB which tilts a large bucket of water DB onto the vegetables. The crank rotates with a constant angular velocity wOA = 4x rad/s. For the instant shown with the crank vertical and the angle 8 = 30° determine...

A four bar mechanism consists of a fixed Link 1= 50 mm, Link 2 = 15 mm, Link 3 = 80 mm and Link 4 = 40 mm. The angle between link 1 and link 2 is 1100. The crank link 2 rotates uniformly at 2X0 rpm (X is the final digit of your matrix number, i.e, 240 rpm). a) Draw the space diagram of the link above. b) Locate all the instantaneous centers and classify them (fixed and permanent...
