A mountain climber, in the process of crossing between two cliffs by a rope, pauses to rest. She weighs 565 N. Find the tensions in the rope to the left and to the right of the mountain climber. 80.0(right side) 65.0°(left side)

Two hockey players check an opponent into boards simultaneously. Player 1 hits from the left at an angle of 37 degrees to horizontal and a force of 400N. Player 2 hits from the left at an angle of 41 degrees to horizontal and a force of 600N. What is the magnitude and direction of total force applied to opposing player

A sign hangs off the side of a building with a beam and a cable. The beam is 3m long and the cable makes an angle of 30 degrees with the beam. If the mass of the sign is 10 kg, what is the tension in the cable? You can assume that the beam and the cable are so light as to be massless. (Hint: find the torques around the point where the beam attaches to the building)

Three forces of A, B & C act on a bolt as shown in the figure below. Where A = 3000 N, B = 2500 N and C = 2700 N. Find the resultant force magnitude and direction. (A 32 B 54° 35° C Resultant Force = 3670 N, Direction = 125° Resultant Force = 3870 N, Direction = 135° Resultant Force = 3550 N, Direction = 115° O Resultant Force = 3950 N, Direction = 105°

The figure below shows a claw hammer being used to pull a nail out of a horizontal board where ? = 27.3°. The mass of the hammer is 1.00 kg. A force of 165 N is exerted horizontally as shown, and the nail does not yet move relative to the board. Assume the force the hammer exerts on the nail is parallel to the nail. A hand uses a hammer to pull a nail out of the ground. The head of the hammer is curved and touches the ground at a single point of contact at the center of the head. The nail in the ground makes an acute angle ? clockwise from the vertical. The nail is hooked in the hammer claw 5.00 cm horizontally to the left of the hammer head's point of contact to the ground. The hand pulls the hammer handle horizontally to the right 30.0 cm above the ground with a force vector F.(a) Find the force exerted by the hammer claws on the nail.magnitude     kNdirection     ° above the horizontal (b) Find the force exerted by the surface on the point of contact with the hammer head.(  î +  ĵ)…

A uniform plank of length 2.00 m and mass 26.0 kg is supported by three ropes, as indicated by the blue vectors in the figure below. Find the tension in each rope when a 710–N person is d = 0.500 m from the left end. Answer the 3 boxes below:

The leg and cast in the figure weigh 220 N (w1). Determine the weight wz and the angle alpha needed so that no force is exerted on the hip joint by the leg plus the cast. 110 N
