Topic: Static Force Analysis

Figure $1$ shows a mechanism that is used to shear thin$-$gauge sheet metal. If a $200-N$ force is applied as shown, determine the force on the sheet metal. The weights of the links are negligible.

$2.$ Figure $2$ shows a mechanism that raises packages in a transfer mechanism. If a $100-$N package sits on the horizontal link while the mechanism is stationary, determine the torque required from the motor. The weights of the links are negligible.

$3.$ A utility lift vehicle is shown in Figure $3.$ Determine the force required by the hydraulic cylinder to maintain the position of the bucket.
