T- tension; A -angle w horizontal
Assuming flag mass is vertical,
vertical component T sin A = 2.9 * g ----(1)
horizontally component T cos A = 14 ----(2)
deviding (1) /(2)
tan A = 2.9*g / 15 = 2.9 * 9.81/15
tan A = 1.8966
A = 62.2 deg
-------------------
Substituting A into (2)
T cos 62.2 = 15
T = 32.16 N

A 205 N sign is supported by two ropes. One rope pulls up and to the right ?1=25.5∘ above the horizontal with a tension ?1 , and the other rope pulls up and to the left ?2=47.5∘ above the horizontal with a tension ?2 , as shown in the figure. Find the tensions ?1 and ?2 . Exit sign suspended by two ropes. Rope 1 goes up and to the right, makes an angle theta subscript 1 with the horizontal,...
A newly planted tree is supported against the wind by a rope tied to a stake in the ground, as shown in the figure below. The force of the wind, though distributed over the tree, is equivalent to a single force F, as shown in the figure. Find the tension in the rope. Assume that neither the tree's weight nor the force of the ground on the tree's roots produces any significant torque about point O. (Let F = 117...
The beam ABC has a mass of 78.0 kg and is supported by the rope BDC that runs through the frictionless pulley at D. The winch at CC has a mass of 44.5 kg. The tension in the rope acts on the beam at points B and C and counteracts the moments due to the beam's weight (acting vertically at the midpoint of its length) and the weight of the winch (acting vertically at point C) such that the resultant...
a sign of mass 20.0 kg is supported at the end of a uniform beam of mass 10.0 kg and length 2.00!m. the beam makes an angle of 30.0 degrees with the horizontal. a wire is attached from the end of the rod to a point on the wall and makes an angle if 20.0 degrees to the horizontal. what is the tension of the wire. what are the magnitudes of the horizontal and vertical components of the reaction force...
A uniform 35.5-kg beam of length ℓ = 5.60 m is supported by a vertical rope located d = 1.20 m from its left end as in the figure below. The right end of the beam is supported by a vertical column.

9) A beam of mass 16 kg and length 1.2 m is supported in two ways: at the wall with a hinge, and by a rope tied to its other end at an angle θ = 34◦ , as Figure 3 shows. At the hinge the wall exerts on the beam a force F of unknown direction and magnitude (shown as a dashed arrow). a) Write three equilibrium equations: for rotation around the hinge (balancing torques), and for translation in...
Rope connected two objects in the inclined plane, A block of mass m1 = 22.9 kg is at rest on a plane inclined at Theta = 35.0 degree above the horizontal. The block is connected via a rope and mass less pulley system to another block of mass m2 = 26.1 kg. as shown in the figure. The coefficients of static and kinetic friction between block 1 and the inclined plane Is MU_s is unknown. If the blocks are released...
A block of mass M is pulled with a rope that exerts a force of a magnitude F, causing it to slide over horizontal ground with kinetic coefficient of friction p (use "mu" when you input your answer). The force is applied at angle theta (use "theta" when you input your answer) above the horizontal shown below. Resolve F into components using the coordinate system shown: F_x, F_y =, Find the sum of the force components in the y-direction acting...
A 3.05-kg object hangs in equilibrium at the end of a rope (taken as massless) while a wind pushes the object with a 14.1-N horizontal force. Find the magnitude of the tension in the rope, and the rope's angle from the vertical. The acceleration due to gravity is 9.81 m/s2 Tension: Number wind Angle: Number
27.2 kg mass is suspended by the cable assembly as shown in the figure below. The cables have no mass of their own. The cable to the left (cable 1) of the mass makes an angle, theta θ1 = 0.00° with the horizontal, and the cable to the right (cable 2) makes an angle, theta θ2 = 38.5°. If the mass is at rest what is the tension in each of the cables, T1 and T2? The acceleration due to...
