17-45. The drop gate at the end of the trailer has a mass of 1.25 Mg and mass center at G. If it is supported by the cable AB and hinge at C, determine the tension in the cable when the truck begins to accelerate at 5 m/s?. Also, what are the horizontal and vertical components of reaction at the hinge C? 30 1.5 m 45°

A 6.0 m long ladder AB leans against a smooth wall making an angle of 60º with the floor (Figure 3). The ladder is uniform and has a mass of 20.0 kg.(a) Determine the forces exerted on the ladder by the floor and the wall (i.e. at A and B, respectively).(b) Determine the minimum value of the coefficient of static friction to prevent the ladder from slipping.

The uniform plank ABC weighs 400 N. It is supported by a pin at A and a cable that runs aroundthe pulley D. Determine the tension in the cable and the components of the pin reaction at A. Note thatthe tension in the cable is constant

The uniform boom shown below weighs 644 N, and the object hanging from its right end weighs 416 N. The boom is supported by a light cable and by a hinge at the wall. 45° | 20° 416 N Calculate the tension in the cable and the force by the hinge on the boom (both in N). (Enter the magnitudes.) tension in the cable force by the hinge N Does the force by the hinge act along the boom? (Assume this force acts along the boom if its direction in degrees above the horizontal is within 2% of the boom's angle above the horizontal.) O Yes O No

A uniform drawbridge must be held at a 37° angle abovethe horizontal to allow ships to pass underneath. The drawbridge weighs45,000 N and is 14.0 m long. A cable is connected 3.5 m from thehinge where the bridge pivots (measured along the bridge) and pullshorizontally on the bridge to hold it in place. What is the tension in the cable?

A 12.0 m boom (along points A to B) of a crane lifting a 3000 kg load, as shown below. The center of mass of the boom is at its geometric center, and the mass of the boom is 1000 kg. a) What is the tension T in the cable? Give your answer in kN = 10-³ N. 171 171 A 188 T b) What is the magnitude of the force at axle A? Give your answer in kN = 10-³ N. 10° 30° B TON Image courtesy of Clker-Free-Vector-Images for the crane. 3000 kg

To facilitate shifting the position of a lifting hook when it is not under load, the sliding hanger shown is used. The projections at A and B engage the flanges of a box beam when a load is supported, and the hook projects through a horizontal slot in the beam. The connections at A and B are smooth. Compute the magnitudes of the forces at A and B when the hook supports a 200-kg mass Assumem - 200 kg, a-280 mm, b-415 mm. Answers: a N N
