Cam mechanisms are used in many machines. For example, cams open and close the valves in your car engine to admitgasoline vapor to each cylinder and to allow the escape of exhaust. The principle is illustrated in the figure below, showing afollower rod (also called a pushrod) of mass m resting on a wedge of mass M. The sliding wedge duplicates the function of arotating eccentric disk on a camshaft in your car. Assume that there is no friction between the wedge and the base, betweenthe pushrod and the wedge, or between the rod and the guide through which it slides. When the wedge is pushed to the leftby the force F, the rod moves upward and does something such as opening a valve. By varying the shape of the wedge, themotion of the follower rod could be made quite complex, but assume that the wedge makes a constant angle of 0 = 19.0⁰.Suppose you want the wedge and the rod to start from rest and move with constant acceleration, with the rod movingupward 1.00 mm in 8.00 ms. Take m = 0.250 kg and M = 0.750 kg. What force F must be applied to the wedge?NINM

19.In the situation shown in the figure, the spring constant is 2000 N/m and the length of the spring when it is neither stretched nor compressed is 80 cm. What is the length of the spring if this system rotates at 10 revolutions per second and if it is in a spaceship far away from all stars and planets (so there is no gravity)? 50 cm 1 kg 1 1 kg (There is no friction.)
A cam, with a minimum radius of 25 mm, rotating clockwise at a uniform speed is to be designed to give a roller follower, at the end of a valve rod, motion described below : To raise the valve through 50 mm during 120° rotation of the cam To keep the valve fully raised through next 30° To lower the valve during next 120°; and To keep the valve closed during rest of the revolution i.e. 90° ; The diameter of the roller is 20 mm and the diameter of the cam shaft is 25 mm. The displacement of the valve, while being raised and lowered, is to take place with simple harmonic motion. c) Draw the displacement, the velocity and the acceleration diagrams for one complete revolution of the cam.
Consider the pictured mass-spring system excited by a mov- ing base y(t) and with a drag force = -e times the velocity of the mass relative to the lab. Find the steady state motion x(t) = X (t) – Xeg representing the displacement from equi- librium (X = natural spring length) relative to the moving base when the cart's motion is sinusoidal y(t) = Y, sin(wt). y(t) (given) X(t) k There are two stages to this problem: a) Derivation of the differential equation. It should come out the form indicated here: Meffë + Ceffå + KeffT = Dÿ+ Eÿ You are advised to use F = ma to derive it. The sum of the forces has two terms, with magnitudes: k times the stretch of the spring, and e times the velocity of the mass relative to the lab. Be careful in your derivation: x and X represent motion relative to the moving base; the mass's acceleration in the frame of the lab is therefore NOT d²r/dt, nor is its velocity relative to the lab equal to dr/dt (think about the position of the mass as described from…

Please answer the question in 5mins I will rate your answer. Cam mechanisms are used in many machines. For example, cams open and close the valves in your car engine to admit gasoline vapor to each cylinder and to allow the escape of exhaust. The principle is illustrated in the figure below, showing a follower rod (also called a pushrod) of mass m resting on a wedge of mass M. The sliding wedge duplicates the function of a rotating eccentric disk on a camshaft in your car. Assume that there is no friction between the wedge and the base, between the pushrod and the wedge, or between the rod and the guide through which it slides. When the wedge is pushed to the left by the force F, the rod moves upward and does something such as opening a valve. By varying the shape of the wedge, the motion of the follower rod could be made quite complex, but assume that the wedge makes a constant angle of ? = 19.0°.

QUESTION 14 The collar of mass m = 77 kg in Figure Q14 slides outwards with an initial radial velocity vo = 0.58 m-s-1 from zero initial radial position (see dashed box) along a smooth rotating shaft (see unit vector ur). The shaft rotates with constant angular speed of w = 2 rad-s-1. Determine the magnitude of the constant force F (N) that needs to be applied in the radial direction (pointing towards the centre of the shaft) in order to decelerate the collar to zero radial velocity the moment when the collar reaches a radial position r = 0.19 m. Consider motion in a horizontal plane, such that gravity can be ignored. Provide only the numerical value (in Newtons) to zero decimal places and do not include the units in the answer box.
