- A temperature sensor is attached to slider AB which moves back and forth through 60 in. The maximum velocities of the slider are 12 in./s to the right and 30 in./s to the left. When the slider is moving to the right, it accelerates and decelerates at a constant rate of 6 in./s2 ; when moving to the left, the slider accelerates and decelerates at a constant rate of 20 in./s2 . Determine the time required for the slider to complete a full cycle, and construct the v–t and x-t curves of its motion.arrow_forwardapplied mechanics 2arrow_forwardA Scotch yoke is a mechanism that transforms the circular motion of a crank into the reciprocating motion of a shaft (or vice versa). It has been used in a number of different internal combustion engines and in control valves. In the Scotch yoke shown, the acceleration of Point A is defined by the relation a=-1.5sin(kt) , where a and t are expressed in m/s2 and seconds, respectively, and k=3 rad/s. Knowing that x=0 and v=0.6 m/s when t =0, determine the position of Point A when t=0.5 s.arrow_forward

Determine the instantaneous angular acceleration of the object at t=2s. Express your answer in units of rad/s2 using one decimal place.arrow_forwardQ6. As shown in the image below, two objects, A and B, are connected using the cable and pulley system. (The cable and pulley system is friction-less and weight-less.) If at this moment the acceleration of object Bis downward 2.3 m/s², determine the acceleration of object A (in m/s²2) at this moment. In this problem, downward motion is considered positive, and in your answer, negative sign must be included if the motion of A is upward. Please pay attention: the numbers may change since they are randomized. Your answer must include 1 place after the decimal point, and proper SI unit. A B VBarrow_forward
- Dynamics of Rigid Bodies problem:arrow_forwardAn automobile travels along a straight road at 15.65 m/s through a 11.18 m/s speed zone. A police car observed the automobile. At the instant that the two vehicles are abreast of each other, the police car starts to pursue the automobile at a constant acceleration of 1.96 m/s . The motorist noticed the police car in his rearview mirror 12 s after the police car started the pursuit and applied his brakes and decelerates at 3.05 m/s . (Hint: The police will not go against the law.) a) Find the total time required for the police car to overtake the automobile. b) Find the total distance travelled by the police car while overtaking the automobile. c) Find the speed of the police car a the time it overtakes the automobile. d) Find the speed of theautomobile at the time it was overtaken by the police car.arrow_forwardDYNAMICS OF RIGID BODIES (RECTILINEAR MOTION WITH CONSTANT ACCELERATION) A body starts with a velocity of 3 m/s and moves in a straight line with a constant acceleration.
