Question

A uniform rectangular block is being held on cart by a hinge at Point A and a roller at Point B (i.e. the block is not attached to Point B and force applied to the block at B is only in the x-direction). The cart is accelerating to the left at 3 m/s. What are the forces being applied to the block at Point A and Point B?

At what value of acceleration would the block begin to lose contact with the roller at Point B?

a. A uniform rectangular block is being held on cart by a hinge at Point A and a roller at Point B (i.e. the block is not att

    The drawing shows a uniform horizontal beam attached to a vertical wall by a frictionless hinge and supported from below at an angle 0 = 42° by a brace that is attached to a pin. The beam has a weight of 350 N. Three additional forces keep the beam in equilibrium. The brace applies a force to the right end of the beam that is directed upward at the angle with respect to the horizontal. The hinge applies a force...

    A uniform rod is attached to a wall by a hinge at its base. The rod has a mass of 6.00 kq, a length of 1.55 m, is at an angle of 29.0° above the horizontal, and is held in place by a horizontal cord attached to the other end of the rod and bolted to the wall above the base of the rod. (a) Determine the tension in the cord. (b) Determine the horizontal and vertical components of the...

    1 point) A block of ice is held 2 m below the surface of the water and then released. What is the magnitude of its initial acceleration? (calculators permitted in this question) m/s2 If its mass is 1.9 kg and its frictional factor is 3 kg/s, what is the terminal upward speed? (Use 920 kg/m2 for the density of ice.) Hint: Use Eqn 13-11, and think about how you need to balance the bouyant, gravitational, and drag forces if you...

    A uniform drawbridge must be held at a 37 ∘ angle above the horizontal to allow ships to pass underneath. The drawbridge weighs 45,000 N and is 14.0 m long. A cable is connected 3.5 m from the hinge where the bridge pivots (measured along the bridge) and pulls horizontally on the bridge to hold it in place. A)What is the tension in the cable? B)Find the magnitude of the force the hinge exerts on the bridge. C)Find the direction...

    A pendulum is attached to the cart that has a mass of 3m and that is free to move along the horizontal direction. From the rest condition, when the lumped mass m of the pendulum makes a 0 angle with the vertical, the pendulum is released. 3m L m Compared to the case in which the cart is fixed (it cannot move), when 0=0°, the speed of the lumped mass at the tip of the pendulum would be smaller.

    (14.2) A block of mass m = 10 kg riding on a frictionless horizontal plane is subjected to five forces. The weight of the block and the normal force of contact with the plane both act in the vertical direction, cancel, and may be henceforth ignored. Three applied forces, →F1 , →F2 , →F3 , act horizontally on the block. The information that we have been able to gather about the applied forces is summarised as follows: F1 = 10...

    A uniform drawbridge must be held at a 33.5 ∘∘ angle above the horizontal to allow ships to pass underneath. The drawbridge weighs 44000 NN, is 10.5 mm long, and pivots about a hinge at its lower end. A cable is connected 3.80 mm from the hinge, as measured along the bridge, and pulls horizontally on the bridge to hold it in place. A. What is the tension in the cable? B. Find the magnitude of the force the hinge...

    A uniform 6-m high, 10-m wide (into the page) rectangular gate is hinged at Point A. The right side of the gate is exposed to the atmosphere while the left side is partially covered by 2 different fluids (oil as top layer and water as bottom layer). The free surface of the oil is 1 m below the hinge at Point A. The oil layer (SG = 0.8) is 2-m thick while the water layer is 3-m thick. Assuming the...
