A crank-rocker mechanism is to be used to drive a ratchet mechanism. Using mathematics and specific illustrations, find the required coupler length in inches required to generate this motion. The swing of the rocker is 35.0 from the vertical position in each direction. (Note: O2 is the crank pivot; O4 is the rocker pivot; C is the coupler-rocker joint; B is the coupler-crank joint). O2O4: 4.1 in.; lies in the horizontal plane O4C: 4.8 in.; mid stroke is vertical

A sliding block C moves along a horizontal line Q2C. A rotation arm Q2B is 4 ft 3 in long and rotates around a center Q2. The connecting rod BC is 8 ft long. This rod is extended to D, making BCD 11 ft 9 in long. Make a drawing of this linkage and trace the path of D while the arm makes 1complete revolution CCW. Locate points for each 15 deg movement of the arm Q2B, beginning with Q2B coinciding with Q2C. Scale: 1 in = 1 ft

Q2BCQ4 is a four bar linkage. Q2 and Q4 are fixed centers on a horizontal line 10 inches apart. Q2B is a link 5 inches long oscillating about Q2. Q4C is a crank 2 ½ inches long which rotates about Q4. BC is a connecting rod 11 ½ inches long. Q2 is left of Q4. A link, EF 6 inches long is pinned to Q2B at E, 1 ½ inches from B. Another link GF 3 ½ inches long is pinned to link BC, 4 inches from C. These links EF and GF are pinned together at F in their upper position. Trace the paths of the points F and G while Q4C makes 1 complete revolution. Find points for each 15 deg position of Q4C and any other necessary in order to secure smooth curve
Given: AB = 0.1 m , CB = 0.4 m, CD = 0.6 m, AD = 0.8 m For the linkage shown below, CD moves back and forth spinning flywheel AB, link CD is the input link. a.) Find the maximum angle in degrees, that is the angle between the extreme positions by the link CD when the circle AB rotates 360 degrees? b.) Why is the wheel able to rotate fully and not get locked up when CD and AB are inline (collinear)? Where's a real life example where this mechanism may be used?

During a bicep curl on a bicep curl machine, I'm curling a weight stack of 100 pounds (single arm...I'm jacked like that). At this very moment, the weight stack has a moment arm of 0.12m, my elbow has an angle of 63deg, my muscle force vector has an angle of 23deg, and it attaches 3cm below my elbow joint on my radius. How much force must my bicep create right at this moment to hold the weight stack in place?

Five masses m1, m2, m3 m4 and m5 are 150 kg, 250 kg, 190 kg , 120 kg and 210 kg respectively. The corresponding radii of rotation are 0.2 m, 0.15 m, 0.25 m 0.1 and 0.3 m respectively and the angles between successive masses are 45°, 75° 20 and 110°. Find the position and magnitude of the balance mass required, graphically, if its radius of rotation is 0.25 m
Her foot pivots as a single structure about a single pivot in her ankle. When she stands on tiptoe, her foot pivots about her ankle. As shown in the foot diagram and the free-body diagram below, the forces on one foot are an upward force on her toes from the floor, a downward force on her ankle from the lower leg bone (called the Tibia), and an upward force on the heel of her foot from her Achilles Tendon. Suppose a 61.3 kg woman stands on one foot, on tiptoe, with the sole of her foot making a 25.0 degree angle with the floor, and with the distances are as shown in the figure.

For the following figure b is the distance to the center of gravity of the arm segment, W is the weight of the arm of mass, m, moving the arm in abduction/adduction. If we had radius of gyration ratio to segment k's (k1 is for the Antero-posterior axis, k2 is the transverse axus, and k3 is for the longitudinal axis of the segment). What is the mass moment of inertia?
