Question: You want to nail a 2.1-kg board onto the wall of a barn. To position the board before nailing, you push it against the wall

You want to nail a 2.1-kg board onto the wall of a barn. To position the board before nailing, you push it against the wall with a horizontal force F to keep it from sliding to the ground. If the coefficient of static friction between the board and the wall is 0.71, what is the least force you apply and still hold the board in place?

2.) An orb- weaver spider sits on in her web that is supported by three radial strands, as shown in the figure below. Assume that only the radial strands contribute to supporting the weight of the spider. If the mass of the spider is 4.4 x 10^-4 kg, and the radial strands are all under the same tension, find the magnitude of the tension, T.
