Please help me with this. I've tried trying to find thethe force required to get the block moving first - but I'm havingno luck. A cement block resting on a borad has a coefficient Fs =0.8. You decide to life the board by raising one end, leavingthe other end resting on the ground. What is the max angleyou can achieve between the board and the ground before the cementblock begins to slide? Please help me with this.
