A servo motor can apply a variable force F, which in its first two S r = 0.25 m is rotating at w = 5 10t N and afterwards is equivalent to a constant force of F = 20 seconds of operation is equal to F N.

The force of the servo motor is applied at %3D exactly half of the horizontal distance to A from the point of contact. Assume the wheel can be treated as a disk and that the braking arm is massless.

A constant moment M in the clockwise direction is applied to a 20-lb thin disk in contact with an inclined surface. The kinetic friction coefficient is at the point of contact D. Determine the magnitude of the angular acceleration of the disk by neglecting the weight of the link AB, if M = 7.5 lb-ft and =0.4. Present your answer in rad/sec² using 3 significant figures. 1 in = 1/12 ft. 9 in. B M 30° D
For the problem related to Fundamental.6 sketches of the system showing: • the respective velocity and acceleration and the frame of reference considered • the forces acting on the system of considered, in other words, a free body diagram (FBD) are mandatory. Their absences will automatically make the problem false. F The 77-kg man pushes on the 120-kg crate with a horizontal force F. The coefficient of static friction between the man's shoes and the surface is 0.82. What must be the coefficient of kinetic friction between the crate and the surface if we observe an acceleration of the crate of 2.1 m/s²? Type your answer in the cell below.

Figure 2 В A Block A is hanging from a massless string which runs over a massless and frictionless pulley and connects to Block B. Block B slides over an inclined plane with ordinary kinetic friction. The plane under block B is inclined at an angle theta = 0 away from vertical. The other side of Block B is connected to another massless string which runs over another massless and frictionless pulley to connect to Cart C. Cart C rolls without friction over a plane which is inclined at an angle of phi = y away from vertical. C
Hi! I need answers in these three questions. Thank you!
block C mass = 99 kg block D mass = 66kg horizontal force (H) = 555N and is applied at block D. Angle = 32.779 degrees note: Ignore friction. Computations must follow D'Alembert's Principle or else the solution is null and void. And answers should be in Newtons or KiloNewtons 1.) Calculate the Normal Force of Contact between blocks D and C. 2.) Determine the Block D Acceleration 3.) Determine the Block C Acceleration
Learning Goal: To use the equations of equilibrium to analyze a system containing a wedge and to determine the necessary applied force to introduce motion into the system. The crate shown is held against wedge B by a spring. The spring is 94.0% of its original uncompressed length 1 = 3.00 m, and the spring constant is given as k = 1650 N/m. The coefficient of static friction at all contacting surfaces is μs = 0.100. The mass of the crate is m = 25.0 kg . The angle is 0 = 14.0°. Neglect the mass of the wedge. Assume the crate only moves in the y direction and that wedge A cannot move. (Figure 1) Figure B < 1 of 1 y L.
