A sign hangs from two wires. The left-hand wire makes an angle of 60° with the horizontal, and the
magnitude of the tension in the wire is 362 N. The right-hand wire makes an angle of 45° with the
horizontal.
Calculate the mass of the sign, in kilograms, to two significant figures.
(Take the magnitude of the acceleration due to gravity, g, to be 9.8m s-2.)
The mass of the sign is
kg (to 2 s.f.)
Two construction workers are lifting a beam using ropes. Worker A pulls with a force of 500 newtons at an angle of 40°with the positive x-axis. Worker B is on the opposite side pulling with a force of 380 newtons at an angle of 115 ° with the positive x- axis. Find the (a) magnitude and (b) direction angle of the resultant force. (Round to the nearest hundredths)

- Solve the following exercises based on Principles 18 through 21, although an exercise may require the application oftwo or more of any of the principles. Where necessary, round linear answers in inches to 3 decimal places and millimeters to 2 decimal places. Round angular answers in decimal degrees to 2 decimal places and degrees and minutes to the nearest minute. a. If AB=7218 and CD=5024 find: (1) 1 (2) 2 (3) 3 b. If CD=4315 and AD=10605 , find: (1) 1 (2) 2 (3) 3arrow_forwardA 50 N force is applied at the end of a 20 cm wrench and makes an angle of 30° with the handle of the wrench. Find the magnitude of the torque. b. What is the maximum torque that can be exerted by a 50 N force on the wrench and а. how it can be achieved?arrow_forwardThree math instructors are trying to hold a sedated bear in the center of a class- room. There are three ropes attached to the bear and each instructor has hold of a rope. Mark is pulling in the direction 15° East of North with a force of 20 pounds and Allison is pulling in the direction 25° East of South with a force of 30 pounds. You must quickly tell Joe the compass direction and the magnitude of the force which must be exerted on the third rope to counterbalance Mark and Allison. (Give approximate answers to three decimal places.)arrow_forward
- A boat (B) is stranded at sea and the coast guard (C) is on it’s way to help. A helicopter (H) is hovering above them at an altitude of 200m. Looking down from the helicopter, the stranded boat is at a bearing of 110° and angle of depression of 35°. The coast guard is at a bearing of 240° with and angle of depression of 50° from the helicopter. If the coast guard is travelling at 30 m/s, how long will it take for the coast guard to reach the stranded boat? Round to final answer to 2 decimal places. (note: bearings are measured clockwise from north)arrow_forwardYou should be able to answer this question after studying Unit 5. A mountain rescue team is preparing to move a stretcher (with an injured climber) down a flat slope. The combined mass of the stretcher and climber is 85 kg, and the slope makes an angle of 18° with the horizontal. The stretcher is held in place by a rope that makes an angle of 25° with the slope. The stretcher is on the point of slipping down the slope. The coefficient of static friction between the slope and the stretcher is 0.15. rope 25° stretcher 18° Model the stretcher and climber as a particle, the slope as a plane and the rope as a model string. Take the magnitude of the acceleration due to gravity to be g = 9.8 ms-2, and round your answers to two significant figures. (a) Draw a force diagram showing the four forces acting on the stretcher. Define the symbols that you use to denote the forces. Choose the Cartesian unit vector i to be parallel to and pointing up the slope, and the Cartesian unit vector j to be…arrow_forward1arrow_forward
- 2. Muscle A and muscle B are attached to a bone as indicated in the figure below. Muscle A exerts a force on the bone at angle a, while muscle B exerts a force on the bone at angle ß. Muscle B Muscle A Bone a. Assume muscle A exerts a force of 900 N on the bone at an angle a = 8°, while muscle B exerts a force of 75O N on the bone at an angle of B = 33°. Find the resultant force and the angle of the force due to muscle A and muscle B on the bone. b. Assume muscle A exerts a force of 1000 N on the bone at an angle a = 9°, while muscle B exerts a force of 820 N on the bone at an angle of ß = 38°. Find the resultant force and the angle of the force due to muscle A and muscle B on the bone.arrow_forward(1) A vertical force P = 150 lb is applied to the handle of the toggle clamp at A as shown.

Reduce the two forces to an equivalent force–couple system at corner O and then specify the coordinates of the point P in the x-y plane through which the resultant of the two forces passes. The cutting surface is 30" x 30".Question 2: Replace the two forces from the original system with a single equivalent force R. This force will pass throught a point P in the x-y plane. Find the distances x and y.The new system looks like this. How big is the force R (enter a positive number) ? Find the distances x and y.arrow_forward
