A tugboat with a displacement¹ of 50 tonnes and resistance² of 750 kN is towing a 75-tonne barge with resistance of 1000 kN. The tugboat has a propeller generates thrust³ of 7 to move it forward, while the barge is non-propelled. Determine the thrust and the force exerted by the rope on the tugboat, given that it takes 35 seconds for the tugboat to uniformly increase its speed to 13.5 knots4. ces: 1. The displacement or displacement tonnage of a ship is its weight. It refers to the weight or mass of water that a ship displaces when it is floating in water. 2. Ship resistance, also known as hydrodynamic resistance, refers to the force that opposes the motion of a ship or vessel as it moves through water. 3. The thrust of a propeller refers to the force generated by a rotating propeller that propels a vessel through water. 4. Knot is a unit of speed used to measure the speed of a vessel. One knot is equal to 0.5144 m/s. 2: OO TT

Trina is a gym goer with a leg length of 84 cm. Suppose that she is in the gym doing straight legraising with 10 lb weights. Compute for the force that the muscle should exert in order to (1) maintain it in the position and(2) lift the weight up given that the distance of the effort (muscle) from the joint is 54 cm,distance of the weight is 80 cm, and the COM is 45 cm from the joint. ANSWER THE QUESTION: 1.) Assuming that the leg moves at 0. 9 seconds, compute for the angular velocity. GIVEN: Leg length = 84 cm = 0.84 m Distance of the muscle from the joint = 54 cm = 0.54 m Distance of the weight = 80 cm = 0.80 m Distance of the COM from the joint = 45 cm = 0.45 m Mass = 10 lb = 4.535 kg Linear displacement x = 38.971 cm Or x = 0.389 m

Trina is a gym goer with a leg length of 84 cm. Suppose that she is in the gym doing straight leg raising with 10 Ib weights. Compute for the force that the muscle should exert in order to (1) maintain it in the position and (2) lift the weight up given that the distance of the effort (muscle) from the joint is 54 cm, distance of the weight is 80 cm, and the COM is 45 cm from the joint. Questions: 1. Draw the free body diagram for straight leg raise. 2. What is the muscle responsible for straight leg raise? 3. What is the fulcrum? 4. What is the effort? 5. What is the resistance?
