The beam ABC has a mass of 78.0 kg and is supported by the rope
BDC that runs through the frictionless pulley at D. The winch at CC
has a mass of 44.5 kg. The tension in the rope acts on the beam at
points B and C and counteracts the moments due to the beam's weight
(acting vertically at the midpoint of its length) and the weight of
the winch (acting vertically at point C) such that the resultant...

F13-4. The 2-Mg car is being towed by a winch. If the winch exerts a force of T = (100s) N on the cable, where s is the displacement of the car in meters, determine the speed of the car when s = 10 m, starting from rest. Neglect rolling resistance of the car. F13-4 A simple beam AB of span length L = 22 ft (Fig. 5-14a) supports a uniform load of Intensity 9 = 1.5 k/ft and a...
4. Field transformations: In the lab frame E 4 V/m, B -3y T, and a point charge q = 1C is observed to be moving with velocity v 2 m/s. a) What is the electric field E' measured in the frame of reference of q? Determine E' by ensuring that the Lorentz force applied on charge q is identical in both reference frames. b) Is this charge being accelerated or not under the influence of fields E and B? Discuss...
Problem #4: The frame supports the triangular distributed load shown Use Mohr's circle to determine the normal and shear stresses at point E that act perpendicular and parallel, respectively, to the grains. The grains at this point make an angle of 45° with the horizontal as shown. Point C is the pin support. 900 N/m 35 75 mmi 200 mm 2.4 m 0.6 m 100 mm 3 m 45° 50 mm 30 mm 1.5 m 100 mm

A spring with natural length Lo and spring constant k is attached to the bead and to a support point a distance h from the wire. See Figure 1. Let z(t) denote the position of the bead on the wire at time t. (Note that x is measured...
Chapter 21, Problem 07 Your answer is partially correct. Try again. A magnetic field has a magnitude of 0.0013 T, and an electric field has a magnitude of 3.6 × 103 N/C. Both fields point in the same direction. A positive 2.6-4C charge moves at a speed of 4.2 x 106 m/s in a direction that is perpendicular to both fields. Determine the magnitude of the net force that acts on the charge. B Ē 9 ✓ 90° X Number...

Instructions: 1. Draw the schematic of the situation described in the wording of the problem. This schematic includes a list of the data given in the wording of the problem, such as initial position (x, yo), initial velocity Ivo, V, Vol, final position (x,y), final velocity (V, V, W) or maximum height (ym). Make a decision on whether you want to use "y" or "h" for the vertical axis and keep it consistent throughout all the problems. Write down the...

(1 point) A mass m = 4 kg is attached to both a spring with spring constant k = 197 N/m and a dash-pot with damping constant c=4N s/m. The mass is started in motion with initial position to 3 m and initial velocity vo = 6 m/s. Determine the position function r(t) in meters. x(1) Note that, in this problem, the motion of the spring is underdamped, therefore the solution can...
