= 4. 3) The hydraulic cylinder D extends, moves the rigid rod ABC, and causes the collar A to move with velocity and acceleration both to the left. If the dimensions ₁ 1.1 ft, and /2 = 2.2 ft, và = 5.8 ft/s, a = 1.2 ft/s², and the angle = 32°, determine the speed of point C. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point, and proper unit.

HW help: Just part c please.

Solve the following application problem: The model s(t) = -16?2 + 5? + 3 describes the height(in feet) of a diver at time ? is measured in seconds. Find the velocity of the diver when the diver hits the water.

A four-bar mechanism is used to transmit power to slider E. Link AC rotates counterclockwise at 100 rpm. A and B are fixed points. The following linkages are measured in cm: AC=35, AB=70, CD=45, BD=45, DE=40. Find the instantaneous velocity of slider E in cm/s 1.Draw the mechanism in appropriate scale on your paper2. Find the instantaneous linear velocity of C3. Find a point on your paper to draw the velocity polygon and scale the magnitude of the computed linearvelocity4. Use the relative velocity equation for finding the linearvelocity of D; ? = ? + ?? ? ?/?5. Remember that although the magnitudes are unknown, their directions can be identified6. Obtain the magnitudes of the unknown velocities from the velocity polygon7. For Link DE, repeat the process by using ? = ? + ??the line as much as needed8. Remember that E is a SLIDER therefore it can only goin the direction where its movement is not constrained? . Add the vector ? to the head of ? and extend?/? ?/??

Steam enters an adiabatic turbine steadily at 6 MPa and 450 °C and leaves at 500 kPa and 250 °C. If the power output of the turbine is 3.9 MW determine the isentrFopic efficiency of the turbine and the mass flow rate of the steam flowing through the turbine. TI Pi T2 P2 %23

We can make assumptions for the unknown value to to be able to find these: Length of swing arm is 19 in, length of sling is 10.5 in Find: A)position vectors for location B and C B) angular velocity for swing arm and sling C) angular acceleration of the swing arm and sling

I need help with this physics problem

A particle is held and then let go at the edge of a circular shaped hill of radius R = shown below. The angular motion of the particle is governed by the following ODE: + 0.4 02 - 2 cos 0 + 0.8 sin 0 = 0 where is the angle in rad measured from the top (CCW: +), ė 5m, as = wis the velocity in rad/s, ==a is the angular acceleration in rad/s². Use MATLAB to numerically integrate the second order ODE and predict the motion of the particle. (a) Plot and w vs. time (b) How long does it take for the particle to fall off the ring at the bottom? (c) What is the particle speed at the bottom. Hint v = Rw. in de all questions the particles inside the tube. /2/07/25 Particle R 0 0 R eled with

Example (3): A body moves on a straight line according to the equation: S = 4 t + 2 t2- 2 t + 5, where (s) is displacement, (t) is the time interva , Find out displacement, velocity , and acceleration when t= 3 sec . Solution: 2 12 - 2 t+ 5
