Muscle force Axis w The mass and length of the forearm in the diagram below are 2.2 lbs. and 0.1 m, respectively. Calculate the torque generated by the weight of the forearm, assuming the weight of the forearm is located halfway along the forearm (1 kg = 2.2 lbs.).
The two uniform bars are identical. The mass and length of each bar are m= 30 kg and L=1.6 m. The top bar rotates around point A, coordinate , locates the bar, and force F(t) = 500 sin 60t (in N) is being applied to the end of the bar. A spring with k = 10000 N/m connects the top bar to a fixed point. The bottom bar rotates around its center at point B and coordinate 0g locates this...
The mass of uniform bar ABC is MBAR = 30 kg and its overall length is L=1.6 m. The bar rotates around point 0 and force F(t) is being to the end of the bar at C. The masses of pistons A and B are ma = 5 kg and mg = 8 kg , respectively. k= 20000 N/m for each spring and c=500 N-s/m for the damper connected to piston A. Coordinate e locates the bar, coordinate x, locates...
#1 A bar of mass m and length 2d sits on a peg that is at a distance d from the end of the bar. If a force of F is applied downward at a point d/2 from the end, what is the resulting torque? a. Fd/2, b.Fd, c. 2Fd, d.3Fd/2 #2 The same bar of mass m of length 2d sits on a peg that is at a distance d/2 from the end of the bar. If a force...
ceiling G 12 Bar AB of mass m and length L is attached to two springs at its ends and is held down with cord C as shown in the diagram. When the bar is horizontal, spring A exerts a force Fo and spring B exerts a larger force F (Cord C is needed to hold the bar in place because both forces F, and F, are greater than the weight of the bar). 1-At what distance x from point...
Enter your answer in the provided box. An iron bar has a mass of 543 g. After the bar had been standing in air for a month, exactly one-eighth of the iron turned to rust (Fe2O3). Calculate the final mass of the iron bar and the rust.
The figure shows the mass m at the end of a bar of length / is restrained by a spring and dashpot. The mass is initially at rest and vibrates in the vertical plane under the action of the force F(1). Determine the equation of motion, natural frequency, and damping ratio of the system when m = 45 kg, k = 9700 N/m, c = 950 N.s/m, a - 0.8 m, and I = 2 m. Neglect the mass of...

Question 1: A 70 kg diver stands at the right end of a uniform 30 kg diving board of length 3.0 m. The board is hinged at the left end and rests on a bar at the 1.0 m mark as shown. Find the vertical force exerted by the bar?
A long thin bar (length L = 18 cm, mass 1.8 kg) of uniform
density is placed upon a horizontal, frictionless surface. A small
rubber puck (mass 250 g) slides towards the bar with a speed (2
m/s) directed perpendicular to the bar. It collides perfectly
elastically with the bar at a distance (d) from the center of mass
of the bar in such a way that the puck rebounds with a velocity (1
m/s).
a) What is the value...
