What is static force analysis? A four bar mechanism has following dimensions: Length of crank=100 mm, Length of coupler link=450mm, length of rocker-270 mm and length of fixed link=250 mm. A force.F=-100i N is applied on to mid-point 'C' of rocker, when crank makes 120° from positive x-axis. Calculate pin forces and torque to be applied on to the crank for equilibrium. 1. A disturbing mass 'm' kg is attached to a shaft. The shaft is rotating at 'n' rpm, The radial distance of the center of gravity of the disturbing mass from the axis of rotation is 'r' mm. It is required that the disturbing mass should not be disturbed by any addition or subtraction of mass. Suggest the ways to balance the system and justify by proper expressions. 2.

A system is being designed to lift objects with a cable. One end of the cableDesign A: Design B: will be attached to the material while the other end will be permanently fixed to a drum (cylinder) so that as the drum is rotated the cable is wound around its outside surface. Two designs for a drum are being considered for use in the system. Design “A” calls for a solid aluminum pulley ( palluminium = 2800 kg/m 3 ) while design “B” calls for a steel pulley (psteel= 8000 kg/m 3 ) that is hollow (it can be modeled as a 12 mm thick shell). Calculate the torque required to accelerate the pulley for Design A to reach 500 RPM in 4 seconds if the pulley is 500 mm wide. Assume constant alpha
3. Figure 3 shows a brake pedal assembly from a car. Under the action of an applied foot force, the pedal lever acts against the fixed pivot and transfers load to the brake cylinder via an actuation rod. The pedal lever is of hollow section, three-sided form with section dimensions as shown in the figure (Section A-A). Via consideration of the pedal lever as a free body, calculate the reactions acting at the fixed pivot and the 10 mm dia. pin. (hint-take the pin and the pivot as supports) Draw the bending moment diagram for the pedal lever and determine the maximum tensile and compressive stresses arising if a force of 1.3 kN is applied at the foot pedal as shown in Figure 3.

M, M2 e friction The figure above illustrates a system comprising a rigid support structure having a cross-sectional shape of a right-triangle. The angle at the top is equal 90° and the angle on the lower-left is 0. The bottom side (hypotenuse) is horizontal and the two remaining sides serve as left-side and right-side inclined planes. A 1ª block having mass Mi is positioned on the left-side inclined plane and a 2nd block having mass M2 is positioned on the right-side inclined plane. An ideal rope under tension T extends from the 1st block parallel to the left-side plane toward an ideal fixed-axis pulley located at the top of the structure. The rope extends over the pulley and then continues parallel to the right-side plane to the 2nd block. The right-side plane is friction-less but the left-side plane has a coefficient of static frietion
