Question

The winch in the diagram is used to move the log AB. We want to know the largest tension in the cable for which the log remains at rest. The log has a mass, m = 150 kg acting at its centroid The coefficient of static friction between the log and the surface :06 The angle of the cable with the horizontal is θ = 40 degrees The length of the log is b = 4 m. Please disregard the thickness of the log. Assume that the log is about to start sliding Calculate the Tension T in the cable. Please include the unit (kN) within your answer and round to 3 significant figures (e g. if the calculated answer was 55.562 kilo Newtons please input: 55.6 kN) Answer: If the log is about to start sliding calculate the normal force, N, under the log. Please include the unit (kN) within your answer and round to 3 significant figures (e.g. if the calculated answer was 55.562 kilo Newtons please input: 55.6 kN). Answer: Assume that the log is about to tip upwards. Calculate the tension in the cable for this condition. Please include the unit (KN) within your answer and round to 3 significant figures (e g. if the calculated answer was 55.562 kilo Newtons please input: 55.6 kN). Answer
